We focus on a setting where users of a real-time networked application need to be assigned to servers, e.g., assignment of hosts to Internet gateways in a wireless mesh network (WMN). The service delay experienced by a user is a sum of the network-incurred delay, which depends on its network distance from the server, and a server-incurred delay, stemming from the load on the server. We introduce the problem of load-distance balancing, which seeks to minimize the maximum service delay among all users. We address the challenge of finding a near-optimal assignment in a distributed manner, without global communication, in a large network. We present a scalable algorithm for doing so, and evaluate our solution with a case study of its application in an urban WMN.

Wireless mesh network (WMN) has become an important leading technology which provides several types of useful applications such as community network, broadband home network and internet access, etc. The rise in the size of users in WMN has created a degradation of efficiency in a network especially in dense areas due to the clumsy channel allocation and hence creating many challenges for enhancing the users experience, network quality and throughput. Therefore in this paper, we proposed OCA based AIF model that can access the channel information and then it process to improve the RF channel association. The proposed OCA-AIF will function for each period when some interference is detected via AIF and we further extend this analysis by taking in to consideration the influence of interference to provide a high quality indicator in network. The analysis of result shows the optimization by our proposed approach which increases as per the increment of relay nodes (RNs).

Wireless networks are truly pervasive in the modern environment: from the workplace and the home, to implanted medical devices. Network security, therefore, is of paramount importance. This volume begins with an overview of the security vulnerabilities of wireless sensor networks, but also offers some means of defence against them. It goes on to propose ways of securing routing in wireless mesh networks. Two further chapters offer in-depth studies of secure and privacy-preserving data protocols for wireless sensor and mesh networks. The book concludes with an overview of the history of homomorphism encryption as a means of securing data, also covering some emerging trends in which this form of encryption offers exciting new possibilities.

Wireless mesh networks (WMNs) consist of mesh routers and mesh clients, where mesh routers have minimal mobility and form the backbone of WMNs. They provide network access for both mesh and conventional clients. The integration of WMNs with other networks such as the Internet, cellular, IEEE 802.11, IEEE 802.15, IEEE 802.16, sensor networks, etc., can be accomplished through the gateway and bridging functions in the mesh routers. Mesh clients can be either stationary or mobile, and can form a client mesh network among themselves and with mesh routers. WMNs are anticipated to resolve the limitations and to significantly improve the performance of ad hoc networks, wireless local area networks (WLANs), wireless personal area networks (WPANs), and wireless metropolitan area networks (WMANs). They are undergoing rapid progress and inspiring numerous deployments. WMNs will deliver wireless services for a large variety of applications in personal, local, campus, and metropolitan areas. Despite recent advances in wireless mesh networking, many research challenges remain in all protocol layers. This paper presents a detailed study on recent advances and open research issues in WMNs. System architectures and applications of WMNs are described, followed by discussing the critical factors influencing protocol design. Theoretical network capacity and the state-of-the-art protocols for WMNs are explored with an objective to point out a number of open research issues. Finally, testbeds, industrial practice, and current standard activities related to WMNs are highlighted.

Wireless mesh network is a key technology for next generation wireless networking. Delay is regarded as a critical component in networks quality of service (QoS) especially the real-time applications become increasingly popular in recent years. In this paper, the queue control system of multi-interface multi-channel (MIMC) wireless mesh networks (WMNs) is modeled firstly, then we analyse the average queueing delay and the average queueing length, and optimize the average queueing delay by more network interfaces as well as transmitting rate of sending interfaces. Finally analytical explanation and simulation using ns-2 simulator show that use ing MIMC strategy in high traffic loading node is a good approach to optimize network performance, the average queueing delay in nodes with dual-channel dual-interface that do not interfere with each other can be reduced by about 30% compared to the single-channel single-interface.

Wireless mesh network is one the most potential application network for outdoor communication. In this presented work the security issues are investigated in WMN and a solution for security issue is designed more specifically for wormhole attack detection and prevention. The issues rise when the nodes are mobile and poor routing techniques allow a user to change or modify the information during data transmission because, during network communication the data is transmitted through the intermediate routers where any node can leave or join the network any time. Thus a malevolent node also can join the network and harm the privacy and security. This given scheme is desired to prepare for the secure communication route discovery which is able to provide the solution for defending routing based attacks in the network one of the attack is wormhole. Thus a novel key is desired to set up for the secure communication route sighting which is able to provide the solution for wormhole link atta...

Abstract. Wireless mesh networks (WMNs) have emerged as a key technology for next generation wireless broadband networks showing rapid progress and inspiring numerous compelling applications. A WMN comprises of a set of mesh routers (MRs) and mesh clients (MCs), where MRs are connected to the Internet backbone through the Internet gateways (IGWs). The MCs are wireless devices and communicate among themselves over possibly multi-hop paths with or without the involvement of MRs. User privacy and security have been primary concerns in WMNs due to their peer-to-peer network topology, shared wireless medium, stringent resource constraints, and highly dynamic environment. Moreover, to support real-time applications, WMNs must also be equipped with robust, reliable and efficient routing protocols so as to minimize the end-to-end latency. Design of a secure and efficient routing protocol for WMNs, therefore, is of paramount importance. In this paper, we propose an efficient and reliable rou...
