A Trust Model for Detecting Device Attacks in Mobile Ad Hoc Ambient Home Network

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.

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.

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.

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.

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.

A product to stream multimedia content with an intelligent control in a home network environment is designed and implemented. The home network used in this multimedia content streaming design consists of a multimedia center, client player (MP3 player or MPEG-I video set-top-box) and a remote control type device (palm pilot PDA). The multimedia center streams MP3 songs or MPEG-I video clips in multicasting mode using real time transport protocol (RTP). The client player receives RTP packets from the multicast channel and decodes the streaming data back to analog signals. Palm pilot PDA gets a list of songs and video clips from the multimedia center and indicates the client machines to playback the contents. The implementation of the whole environment and its operation are under Linux OS with various applications, tools and packages.

Advances in electronics and connectivity have enabled a wide range of applications that can harness data collection for better decision making and an improved lifestyle. The Internet of Things (IoT) provides the communication infrastructure that allows devices with sensing and control capabilities to be connected within a home network. Smart home systems are considered one of the prominent applications in IoT, where it is possible to control home devices to achieve a better usage in terms of cost and comfort. However, smart home networks contain a wide range of devices and finding an optimal schedule for their working hours is an NP-hard problem. Hence, rather than using mathematical optimization to find optimal solutions, this paper proposes a modeling and simulation methods in order to provide good decisions and recommendations for devices’ scheduling. Discrete Event System Specification (DEVS) formalism is used to develop a model of a smart home network. The devices are categorized into two groups: monitoring devices and control devices. Monitoring devices include sensors that capture climate, energy, power, performance, and occupant’s behavioral data. Control devices send signals remotely for setting and controlling different devices in the smart home network. The behavior in terms of power usage and cost is simulated under different scenarios and settings. The simulation results show that less energy consumption can be achieved if users adopt a behavior where the schedule of three devices is changed every week. As a result, the proposed method can be utilized to make better decisions in setting devices parameters and evaluating the performance of the smart devices network under different conditions, scenarios, and settings.

This paper proposes a novel object-based home network middleware for the interoperability among home devices and smart grid devices. This middleware can be adopted by home devices for energy efficient homes.

In this paper, the author describes the design and implementation of a LDNA (Digtal Living Network Alliance) Framework for Handheld devices. DLNA has developed guidelines for interoperability among home devices enabling a multitude of usage scenarios for sharing digital content such as A V (Audio Visual), Photo, and Audio. The proposed DLNA (Digital Living Network Alliance) Client Framework handles multiple services like Video and multimedia services in Smart Home networks simultaneously. With this new DLNA framework, the home users can choose various services dynamically and use them with out any complicated pre-configuration with the Home IMS gateway (HIGA). The framework provides smooth data transfer switching in home network between Cellular and Wi-fi/Bluetooth networks to enhance mobility based on user/application preferences. The DLNA Framework also provides QoS measurement and monitoring functionality for multimedia services, which enables users to benefit from high throughput and maintains session continuity during selection of different access networks. Apart from these features, the DLNA Framework provides access to device access protocols like UPnP to facilitate the management of home devices.

To maintain network efficiency of a home network, it is crucial to moderately distribute limited data throughput and bandwidth resources to various home devices and services that require different network resource provisions. This paper accounts for QoS differentiation and fairness of network resource allocation which are essential to the design of an efficient IoT-based home media delivery mechanism against network traffic dynamics. Accordingly, our study in this paper proposes a QoS-prioritised media delivery mechanism with adaptive data throughput. This mechanism design includes several functions: assigning weights of relative importance to home service types, adjusting media quality of home services, reducing data workload against traffic congestion, and fairly distributing free bandwidth to prioritised home services. Furthermore, our study fulfills a simplified proof-of-concept implementation in a small-scaled IoT-based home network. Practical experiments can generate real measure data for performance examination. Results show that the proposed mechanism is able to sustain not only QoS differentiation like data throughput and delay, but also fair user satisfaction with comfortable media playing quality.

Internet of everything (IoE) has the power of reforming the healthcare sector - various medical devices, hardware, and software applications that are interconnected, tendering a massive volume of data. The huge interconnected medical-based network is prone to significant malicious attacks that can modify the medical data being communicated and transferred. IoE permits dynamic two-way communication and empowers the network with intellect, sophisticated data handling, caching, and allocation mechanisms. In this paper, an improvement in the conventional variable-sized detector generation for healthcare - IVD-IMT algorithm under Artificial Immune System (AIS) based Intrusion Detection System (IDS) capable of handling enormous data generated by the IoE medical network is proposed. Algorithm efficiency is dependent on two performance metrics - detection rate and false alarm rate. The input parameters were tuned using synthetic datasets and then tested over the NSL-KDD dataset. The research lays emphasis on lowering the false alarm rate without compromising on the detection rate.

The Gossip-Based Relay Protocol (GRP) is developed based on Ad Hoc on Demand Distance Vector Protocol (AODV) and proposed to increase the efficiency of package routing functionality in ad hoc networks through specific flooding scheme. This lightweight protocol reduced the collisions on the network through specific mechanisms. Request to Send/Clear to Send (RTS/CTS) mechanism is widely used in ad hoc environment with Temporarily Ordered Routing Algorithm (TORA) in order to eliminate collisions and allow access to the shared medium through proposed authentication methods. Since GRP contains specific mechanism of directed acyclic Graph (DAG) mechanism to mitigate overhead problem, RTS/CTS modified TORA might result in similar performance metrics. In this paper, TORA protocol has a modification of new RTS/CTS mechanism and has been simulated in order to be compared with proposed lightweight robust forwarding GRP scheme in terms of specific performance metrics such as network throughput, end-to-end delay and message flooding rate over the network through OPNET simulation package in order to expose the optimal solution to increase overall network throughput in ad hoc environment.

This is a report on the Workshop on Tracking Quality of Experience in the Internet, held at Princeton, October 21--22, 2015, jointly sponsored by the National Science Foundation and the Federal Communication Commission. The term Quality of Experience (QoE) describes a user's subjective assessment of their experience when using a particular application. In the past, network engineers have typically focused on Quality of Service (QoS): performance metrics such as throughput, delay and jitter, packet loss, and the like. Yet, performance as measured by QoS parameters only matters if it affects the experience of users, as they attempt to use a particular application. Ultimately, the user's experience is determined by QoE impairments (e.g., rebuffering). Although QoE and QoS are related---for example, a video rebuffering event may be caused by high packet-loss rate---QoE metrics ultimately affect a user's experience. Identifying the causes of QoE impairments is complex, since the impairments may arise in one or another region of the network, in the home network, on the user's device, in servers that are part of the application, or in supporting services such as the DNS. Additionally, metrics for QoE continue to evolve, as do the methods for relating QoE impairments to underlying causes that could be measurable using standard network measurement techniques. Finally, as the capabilities of the underlying network infrastructure continues to evolve, researchers should also consider how to design infrastructure and tools can best support measurements that can better identify the locations and causes of QoE impairments. The workshop's aim was to understand the current state of QoE research and to contemplate a community agenda to integrate ongoing threads of QoE research into a collaboration. This summary report describes the topics discussed and summarize the key points of the discussion. Materials related to the workshop are available at http://aqualab.cs.northwestern.edu/NSFWorkshop-InternetQoE.

Mobile Ad hoc Network is an emerging research area with practical applications. Due to its fundamental nature, however, a malicious attack may disrupt the route discovery process and significantly affect the Quality of Service delivered by the network In this paper, we introduce a new secure routing protocol, Secure On-demand Source Routing (SOSR), which follows a number of basic techniques of ad hoc on-demand routing protocols. Our protocol is based on promiscuous receive mode, successfully defeats different types of identified attacks and detects misbehaviors of abnormal nodes. The only requirement of the protocol is a shared key between the communication end nodes. In particular, the scheme offers low processing overhead for intermediate nodes of the network.
