Design and Implementation of UPnP-Based Surveillance Camera System for Home Security

This paper discusses the benefits of a proposed Session Initiation Protocol (SIP)-based device communication Service for deployment on a Mobile Open Services Gateway Initiative (OSGi) framework. Mobile OSGi deployment provides a gateway to a mobile user’s Personal Area Network (PAN). When the SIP Service is deployed in OSGi, it is possible to bridge multiple devices and gateways, offering device and service mobility as users traverse multiple mobile and home networks. Additionally, the SIP Service provides protocol bridging via bridging bundles and grants application layer mobility to OSGi services. In this paper, we discuss a novel architecture, based on the deployment of the SIP Service in a mobile OSGi framework, which effectively delivers PAN and home network device interoperability. Finally, we offer a use case scenario and analysis of its implementation using our proposed architecture.

현재 여러 종류의 홈 네트워크(home network) 기술들이 존재하고 있으며, 단일화된 홈 컴퓨팅(home computing) 환경을 위해서는 서로 다른 네트워크 프로토콜간의 연동이 필수적이다. 이를 위하여 여러 종류의 홈 네트워크 미들웨어(home network middleware)가 개발되었고 특히 OSGi (Open Service Gateway Initiative)는 다양한 미들웨어 환경 사이의 서비스 상호연동을 제공하기 위해 제안되었다. 그러나 OSGi의 실행환경인 프레임워크(framework)는 수동적으로 서비스 번들(service bundle), 사용자 및 장치 관리 등을 수행하는 취약점을 가지고 있다. 본 논문에서는 사용자들의 편의성을 위해 수동적으로 관리되는 부분들의 문제점을 개선하고자 한다. 이를 위하여 자동화 서비스와 효율적인 서비스 번들의 관리를 위한 SBM (Service Bundle Manager)의 구조를 제안하고, SBM을 구현하여 SBM의 실효성을 검증하였다. Since different kinds of home network technologies coexist, seamless connections between different kinds of network protocols are essential for home computing environments. Several kinds of home network middleware have been developed and OSGi(Open Service Gateway Initiative) was initiated mainly for interoperability support with service distribution between various middleware environments. Framework, OSGi service platform, has weaknesses of passive service bundle management, user management and device management. Therefore, this paper resolves passive management parts which are critical weaknesses of OSGi Specification Version 3 and proposes SBM (Service Bundle Manager) to effiently manage various service bundles. Additionally, we verify practical effects of SBM through experiments.

Several kinds of home network middleware have been developed and OSGi (Open Service Gateway Initiative) was initiated mainly for interoperability support with service distribution between various middleware environments. In this paper, we analyze the weaknesses in the OSGi service platform, such as a non-distributed framework, passive user management, device management, and service bundle management. Moreover, we propose SBM (Service Bundle Manager) to efficiently manage various service bundles. This paper concludes with the implementation results for SBM.

This paper introduces MyHome, a framework of smart home by which household information is all at a finger tip. Through adopting Message oriented middleware (MOM) and open service gateway initiative (OSGi) technologies, MyHome offers reliable automatic operations, fault tolerant and configurable home automation, high extensibility and large scalability. In its design, MyHome system is composed of a residential gateway MyServer and Internet accessible GUI MyIcon and MyMobile. MyServer is used to provide services regarding home security, inventory tracking, facility management, GPS location recording and family care. Inherently an interactive and multitasking system driven by peripherals connected through wireless sensor networks, the overall MyServer architecture is designed with six core service modules operating on a MOM. Each of these modules is designed as an OSGi bundles and is implemented by a programming template utilizing event publish/subscribe messaging mechanism. To facilitate program demonstration, simulator and scenario editor are also developed. A successful implementation of the proposed MyServer is also demonstrated in an emulated home environment where peripherals are connected through ZigBee wireless sensor network with data integrated into a database. With these clearly defined service modules and pertinent infrastructure to integrate household peripherals, this paper presents a practical approach to the implementation of a smart home.

Energy-saving is a very important issue in resent years. To provide a management platform of energy-saving in the digital home can save more power when using the home appliances. In this paper, we design a management platform for energy-saving based on open service gateway initiative (OSGi), remote management server (RMS) and home automatic network (HAN) technologies. Simulation results show that the proposed system is a better solution for home energy-saving.

The rapid development of advanced mobile technologies and wireless Internet services has accelerated the explosion of the mobile service market. Such an extension encourages an increasing number of users engaging in mobile applications. However, the challenge of designing “useful” mobile applications still remains. To overcome this challenge, this study conducts a systematic review of mobile applications, identifying a set of heuristics and relevant features in mobile applications design. More specifically, seven usability heuristics, namely navigation, content, error handling, consistency, functionality, cognitive load and aesthetic design have been developed for mobile applications. The results identify a number of design features based on the proposed usability heuristics, and the associated requirements of usability heuristic to mobile physical constraints are described. The major contribution is to propose a systematic analysis of mobile application usability for mobile developers and designers.

Traffic management in home area networks (HANs) is different from the traditional traffic management in access and core networks. Traditionally HAN traffic works in best effort fashion and the HAN services are usually accommodated on the basis of first-in first-out rule. However quality can deteriorate when high number of users is connected to the HAN. Moreover the bursty traffic can also impact the quality by chocking the network traffic and blocking the network resources for all other traffic. Traffic management rules can be employed in HAN to prioritise different types of traffic according to user requirements. Dynamic configuration of network resources and services is multifaceted process, which requires many skills and knowledge. Policy-based Traffic Management (PBTM) can play a significant role in managing home networks and configuring the services dynamically according to HAN user requirements. This paper presents a testbed model for HAN to simplify traffic management process based on the principles of policy-based network management.

Recently, smart phones such as the Galaxy S and IPhone, and tablet PCs such as the Galaxy Tab have been introduced and become widespread in the market, thus the environment for wireless Internet services has been improving. As the market has improved, consumer preferences for mobile devices and the relationship between these devices and wireless Internet services regarding consumer preferences have become a very important issue. However, although there have been a considerable number of studies on the demand for mobile devices, it is not easy to find previous studies on the relationship between consumer preferences for specific attributes of wireless Internet services and the demand for mobile devices. The main purpose of this study is to analyze which mobile device is more likely to be preferred or become the main channel for wireless Internet services and how the demand for each mobile device is influenced by consumer preferences for specific attributes of wireless broadband Internet services used on it, and to induce managerial implications based on the main findings. To derive the results on consumer preferences, conjoint analysis is used. The survey was conducted using 1,000 Korean consumers. In the survey, respondents are allowed to choose more than one hypothetical alternative representing a mobile device combined with a certain type of wireless broadband Internet service if they desired. To estimate the consumer preferences quantitatively, a multivariate probit model is used. According to the estimation results, owing to their portability, smart phones are more likely to become a major channel for wireless Internet services despite their drawbacks in terms of display size and performance. Portability is the most important factor affecting the choice of a mobile device when using wireless Internet services. Therefore, manufacturers of mobile devices for wireless Internet services should improve the overall functionality and performances of mobile devices without negatively affecting portability. However, at the same time, consumer preferences for specific attributes of wireless Internet services are found to affect the demand of each mobile device much differently. Therefore, the prediction that smart phones will be the prevalent mobile device for use of wireless Internet services can be somewhat changed, depending on which and how wireless Internet services are provided to each mobile device and how they affect the demand for each mobile device. As mentioned above, there are significant differences between mobile devices with regard to the effects of mobility, data transfer speed, type of contents or Internet interface for wireless Internet services. It is found that the mobility of wireless Internet service is highly valued for smaller devices, but not much for notebook PCs. In contrast, data transfer speed and similarities in the type of contents or Internet interface to those provided by fixed broadband Internet services become more important for larger mobile devices. Thus, it is necessary for wireless Internet service providers to differentiate and optimize their contents and Internet interfaces properly for various mobile devices. Additionally, it is reasonable that manufacturers of smart phones focus on mobility and portability (or convenience) rather than adding sophisticated functions or pursuing higher-level specifications. Further, for smart phones, for which mobility and convenience are important, wireless Internet service providers should develop and provide easy and convenient programs, rather than advanced programs that require high device performance. Lastly, with respect to individual demographics, young and highly educated people are more likely to be consumers of newly introduced mobile devices for using wireless Internet services. Therefore, these young and highly educated consumers should be considered a major target for manufacturers of mobile devices for wireless Internet services.

Wireless mesh networks (WMNs) that are being increasingly deployed in communities and public places provide a relatively stable routing infrastructure and can be used for diverse carrier-managed services. As a particular example we consider the scenario where a mobile device initially registered for the use with one wireless network (its home network) moves to the area covered by another network inside the same mesh. The goal is to establish a secure access to the home network using the infrastructure of the mesh. Classical mechanisms such as VPNs can protect end-to-end communication between the mobile device and its home network while remaining transparent to the routing infrastructure. In WMNs this transparency can be misused for packet injection leading to the unnecessary consumption of the communication bandwidth. This may have negative impact on the cooperation of mesh routers which is essential for the connection establishment. In this paper we describe how to establish remote connections inside WMNs while guaranteeing secure end-to-end communication between the mobile device and its home network and secure transmission of the corresponding packets along the underlying multi-hop path. Our solution is a provably secure, yet lightweight and round-optimal remote network access protocol in which intermediate mesh routers are considered to be part of the security architecture. We also sketch some ideas on the practical realization of the protocol using known standards and mention extensions with regard to forward secrecy, anonymity and accounting.

The emergence of mobile Internet of Things (IoT) has brought much more convenience to our daily life than ever before, modern intelligent vehicles are usually equipped with various mobile IoT components or devices. However, when we are enjoying the convenience from the rapid development of mobile IoT services, our privacy can be misused by attackers in an easier way. In this paper, we devise a query scheme with intelligent vehicle privacy guarantees, which enables a vehicle to acquire accurate query service from the service provider (SP) without providing its explicit private information, such as location or query interest privacy. And more than that, we introduce network coding for the first time to make our scheme applicable to a more sophisticated top-K query by multiple vehicles cooperation in mobile IoT. Furthermore, we also consider the unnecessary reveal issue of service data at SP side since the data is its asset. Performance analysis and experiments verify the validity of our scheme and demonstrate a better accuracy and efficiency compared with existing solutions in mobile IoT scenario.

Users are increasingly nomadic and want to access their home network from anywhere. Such remote access might also be granted for family members or friends and controlled by the home network owner on a per device basis. This paper describes an overall sound solution for a layer 2 VPN, providing one-click access to the home network. Layer 2 VPN transports all home network protocols, including multicast, UPnP, Windows shares, thus providing full home network experience to remote users. Our solution addresses several practical and technical is- sues such as MAC address filtering and IP collisions. Our solution enables in particular per-device security policy enforcement while sharing the same access credentials with several remote users. We implemented and tested the solution by extending OpenVPN and a home gateway.

This paper considers SDN, and OpenFlow in particular, as technology to develop the next generation of more flexible, configurable and automated home networks. We identify the problems with the current state of the art in home networking, which includes a lack of user engagement in home network maintenance and configuration, Internet bandwidth limitations, and a lack of ISP reconfiguration and troubleshooting tools. We propose HomeVisor, a novel remote home network management tool. In this paper, we evaluate HomeVisor's ability to outsource control to an entity outside the home network. This includes the overhead of multiple slices within the home, and the effect of controller latency on network performance.

Power Line Communications (PLC) is regarded as the promising home networking technology for smart grid application since the PLC technology enables data transmission via the existing power line. The cooperation between PLC and Wireless Local Area Network (WLAN) will be an effective hybrid solution for Home Area Networks (HANs). In this paper, we consider that Transmission Control Protocol (TCP) packets are transmitting in heterogenous communications network based on PLC and WLAN. The existing TCP congestion control has low effectiveness due to the error-prone power line channel. Therefore, we propose an adaptive rate control to improve TCP performance in the hybrid PLC/WLAN HANs. We exploit the communications mechanism of WLAN to improve the PLC link utilization. The methodology of Heuristic Dynamic Programming (HDP) is employed to obtain the optimal rate policy. The bottleneck link capacity is estimated by neural network training. The sending rate is adapted according to the long-term quality of service (QoS) of applications. Simulation results illustrate that the proposed rate control effectively filters out the negative impact from the instantaneous impulse noise in PLC channel and outperforms the existing TCP.

<p>The mobile industry in recent years has been growing at a speedy pace where the use of cell phone is no longer limited to conventional usage like the voice communication, but has enriched the customer experiences with mobile internet services and other value added services. Along with the growing mobile industry, technology behind it is also changing accordingly. However, the user acceptance of technology depends on various factors that lead to either user acceptance or rejection. This study thus aims to identify the major determining factors that influence the user to use the 3G mobile internet and examines the interrelation among the determinants along with effect of the demographic variable limited to Kathmandu Valley users. The conceptual framework of this study is based on the extended version of Davis (1989)’s technology acceptance model using variables social influence, price perception, perceived usefulness, perceived ease of use, attitude to use and behavior intention. The primary survey is conducted using a set of questionnaire, which produced 180 valid responses from the mobile users in Kathmandu Valley. The reliability of the data from questionnaire is verified with factor analysis and Cronbach’s alpha. The result shows that social influence has significant influence on perceived ease of use while it has no significant influence on perceived usefulness. Price perception, on the other hand, influences the perceived usefulness. Similarly, perceived usefulness and perceived ease of use influence the attitude of use, which finally influences the behavioral intention. Along with this, social influence is also found to be the extended factors that can influence the attitude of the users, which in turn affects the behavioral intention. Demographic variables, however in this study, have shown no significant influence on the behavioral intentions. On the whole, the usage of 3G mobile internet service is not seen to be satisfying from the study. The major reasons as surveyed from the users themselves for this lower utilization seems to be higher data costs, presence of cheaper alternatives for internet like Wi-Fi internet, quick drainage of battery and slow mobile internet service provided by the mobile service providers. Thus, for mobile service providers, internet service providers are their direct competitors for 3G mobile internet services. This paper enhances understanding of user acceptance of 3G mobile internet services.</p><p>Journal of Business and Social Sciences Research, Vol. 1, No. 2, pp. 135-152</p>

IPTV is considered a stepping stone into a ubiquitous area as the home networks' main business model. We propose the P2P chord service overlay network model to provide services and make sharing resources among mobile devices easy. The proposed SGN (Spot-based Group Network) uses hierarchical service delivery network architecture. It delivers services and resources among distributed mobile devices. We suggest three business models which are plausible ubiquitous service architectures.
