QoS-prioritised media delivery with adaptive data throughput in IoT-based home networks

PurposeThe number of home networks, as well as the number of services and hosts in them, is increasing. Often home users cannot get public IPv4 network allocations from service providers and are forced to use network address translation (NAT) and port forwarding to solve connectivity issues to the different home services. This paper seeks to introduce a secure connectivity solution utilising both IPv6 and IPv6 transition mechanisms in cooperation with existing virtual private network (VPN) solutions.Design/methodology/approachThe proposed solution to avoid route conflicts and other problems with private IPv4 address space collisions is to utilise 6to4, an IPv6 transition mechanism, to obtain routable IPv6 network addresses first for the home network and services and then, to utilise the same IPv6 network for connectivity by bridging it over a VPN connection to the mobile terminal.FindingsThe paper finds that the adoption of this solution and these technologies will depend on how useful they are seen by vendors or service providers and included in their products. Regular vendors and service providers probably want to wait until there is a greater customer need. On the other hand, customers do not know about the possibilities before they are shown to them in practice. The best approach to this challenge is to find a cooperating vendor, or even better, a service provider willing to develop the concept further and to integrate it into the devices and services they are already offering.Originality/valueThe technologies for enhancing home service connectivity are already available. In the proof‐of‐concept implementation the paper has shown that all these components can be integrated and utilised to build home routers for present and future home networks. The technical disadvantages and challenges are solvable with further work and the whole concept is ready to be turned into products and services. As indicated in the paper, one of the issues for further work is to find and convince a vendor or service provider to integrate the proposed solution in their home router.

The explosive growth of Internet-connected consumer devices in the digital home has made home networks one of the important emerging topics in networking research. A rich body of research efforts have been made to study broadband performance and home network management, little is known about network traffic that are exchanged within home networks or between Internet-connected devices in home networks and end hosts on the Internet. In this paper we design and implement a built-in traffic monitoring system on programmable home routers to collect and analyze incoming, outgoing and internal traffic for residential home networks. To illustrate the applications of the proposed built-in traffic monitoring system, we deploy the system in two real home networks, and demonstrate its capabilities of detecting unwanted traffic towards home networks as well as those suspicious traffic originating from compromised devices in home networks. In addition, our correlation analysis on unwanted traffic towards distributed home networks reveals aggressive scanners on the Internet and sheds lights on traffic characteristics of these scanners.

Wireless sensor networks (WSN) have recently been proposed for a large range of applications in home and industrial automation, and for health and environment monitoring. Especially the ZigBee standard is getting rising attention as it can be used to implement wireless sensor networks, because of its low data rate and low power consumption. Increasingly there is a need to access wireless sensor network services from other IP- based networks. The DPWS has been chosen to implement the integration of the different forms of networking services. DPWS uses web services, XML, WSDL and SOAP protocol to connect various devices and services in home and industrial applications. It allows collaboration and dynamic reconfiguration of network services and devices. This paper will describe our idea of how DPWS can be used to integrate a wireless sensor network into other IP-based networks.

Smart home automation technologies have been commercially available already, however the interoperability problems of different hardware and software components, the limited service scalability and the complexity of configuration and use prevent their mass adoption. In this paper we present a Connected Home Platform and Development Framework for easy design, development and deployment of smart home services offering a wealth of new exciting smart home experience on top of existing broadband service bundles. The Home Controller is used to integrate connectivity with home devices of various home control technologies. The Service Platform embeds the use of OSGi technology in the Home Controller that enables the OSGi-literate engineer to quickly develop and deploy home services utilising the widely adopted automation technologies. The different home network subsystems are interfaced in a common way through the Network Adaptation Layer, a set of OSGi components known as ROCob. Following the ROCob API Specification, a developer may build various applications, such as presentation layer applications (e.g. a web based UI), monitoring applications that collect data and send them to a backbone server, and other home control and pervasive applications.

Wireless sensor networks have become an essential part of home and building automation, especially for energy management and health monitoring. This paper presents a Distributed Operating System (DOS) based on the Service-Oriented Architecture (SOA) to manage all embedded devices in a home network at high level of interoperability. This system can solve many problems related to accessing home network from Internet and future networks like Smart Grids. The proposed system takes into consideration the limited resources of sensors as well as the matters of simultaneous multi-access, eventing, authorization, security and scheduling the on-line time of sensors in order to reduce power consumption. The paper shows the advantages of using some features of our SOA distributed operating system, like using a queue with a dispatcher to dispatch the simultaneous web requests and also using cache and scheduling, in addition to using a requester to enable accessing embedded devices with different networking protocols. These features help in increasing the quality of services and reaching high level of reliability.

To support any services in all-IP networks, it is necessary to allocate both computing resource and network resource (bandwidth) simultaneously and effectively. The authors proposed the joint resource allocation method for multiple resource types, assuming the non-delay resource allocation. Although the proposed method can achieve an efficient use of resources, it may result in an unfair use of resources in which resources may be monopolized by a specific service. Therefore, the authors proposed the fair joint multiple resource allocation method which tries to equalize the total amount of resource allocated to each service. This paper proposes to enhance the fair joint resource allocation method, assuming three or more services and unbalanced generation traffic. It is demonstrated by basic simulation evaluations that the enhanced fair joint resource allocation method could enable fair resource allocation among multiple services without a large decline in resource efficiency.

Though many services are developed and provided for digital homes, a user would both pay for a physical device (appliance) and supporting software (applications and/or services). However, a service or an appliance may only be needed in a period, such as a rental service, or a trial usage. Hence we propose a “Try before you buy” solution for networked digital home appliances and services. The idea is to have an authentication scheme to identify the appliance and/or the service based on the device in reasonable legal use at the right place and in the right time period. The appliance has the ability of self checking about the rental agreement and target environment (the user information), and the appliance or the service based on it connects to the home network gateway to check the lease term itself or check with the service provider.

Smart homes integrated with sensors, actuators, wireless networks and context-aware middleware soon becomes part of our daily life. This paper describes a context-aware middleware providing an automatic home service based on a user's preference inside a smart home. The context-aware middleware includes an appliance controller, a context-aware agent and a scalable browser. The appliance controller takes charge of communication between appliances in the context-aware middleware. The context-aware middleware use OSGi (open service gateway initial) as the framework of the home network. The scalable browser recognizes the properties of all the rendering device, and it figures out their screen size. We use UlML (user interface markup language) as multiple rendering device. The context-aware agent utilizes 6 basic data values for learning and predicting the user's preference for the home appliances: the pulse, the body temperature, the facial expression, the room temperature, the time, and the location. The six data sets construct the context model and are used by the context manager module. The user profile manager maintains the history information for home appliances chosen by the user. The user-pattern learning and predicting module is based on a neural network, which predicts the proper home service for the user. The test results show that the pattern of an individual's preference can be effectively evaluated.

This study designed, simulated and evaluated the performance of a conceptual framework for ambient ad hoc home network. This was with a view to detecting malicious nodes and securing the home devices against attacks. The proposed framework, called mobile ambient social trust consists of mobile devices and mobile ad hoc network as communication channel. The trust model for the device attacks is Adaptive Neuro Fuzzy (ANF) that considered global reputation of the direct and indirect communication of home devices and remote devices. The model was simulated using Matlab 7.0. In the simulation, NSL-KDD dataset was used as input packets, the artificial neural network for packet classification and ANF system for the global trust computation. The proposed model was benchmarked with an existing Eigen Trust (ET) model using detection accuracy and convergence time as performance metrics. The simulation results using the above parameters revealed a better performance of the ANF over ET model. The framework will secure the home network against unforeseen network disruption and node misbehavior.

This article developed a framework for trust management in mobile ambient home network with a view to secure the home devices and channel against attacks. The framework was design using mobile ad hoc network and social networking concept. The trust management, global reputation aggregation which considered the direct and indirect communication of home devices and remote devices was employed to shield home devices from attacks. While real time dynamic source routing protocol was employed to prevent the channel from attacks by selfish and malicious nodes. The prototype of the framework was implemented using C# programming language. The framework will enhance the activities in the home by securing the home network against unforeseen network disruption and node misbehavior due to the distributed nature of the environment.

New networking challenges are arising in home networks which will host advanced services in the future. In this paper, we look at home networks as they are managed today, and attempt to identify difficulties that will arise in future when advanced usage is desired. We discuss how IPv6 and standardised IPv6 transition technologies assist in deploying advanced services from home networks. Our practical experiences and experiments with bringing IPv6 to home networks using 6 to 4, building an experimental prototype home gateway device, as well as deploying image sharing, data and streaming audio services from these networks are detailed

Because of the advanced development in computer technology, home automation system could provide a variety of convenient and novel services to people. But only providing many kinds of services is not enough; instead, upgrading the quality of services is also a very important issue. One way to upgrade the service quality is to customize the service according to the inhabitant's personal situation, and the user location is the key information for the home automation system to customize the services. Another impact of the advanced computer technology is to make the personal digital device to commonly have the capability to communicate through the wireless networks, and the popularity of wireless networks in home has increased in recent years. As a result, home automation system can bring services to personal digital devices held by people through any wireless network, and customize the services according to the location of personal digital device in home. In this paper, we present a location determination system for the home automation system to provide location aware services. This location determination system uses support vector machine to classify the location of a wireless client from its signal strength measures, and we describe its architecture and discuss its performance.

The rapid growth of broadband connections and home networks has created new application opportunities such as video streaming and remote health care. However, managing and securing the increasingly complicated home networks has remained a serious challenge for most home users who have little technical expertise to manage their home networks and connected devices. Towards this end, we will demonstrate HomeTPS, a traffic profiling system for home networks that collects, analyzes and makes sense of home network traffic. The demonstration will show automatic traffic collection from programmable home routers, informative traffic summary reports and behavior profiles for Internet-capable home devices, and real-time discovery of anomalous traffic from Internet attackers or from compromised devices in home networks.
