Mobile relay stations (RSs) provide broadband wireless access (BWA) networks with additional mobility, which extends network coverage and advances dynamic networking and ubiquitous computing. However, there are many unresolved security vulnerabilities in the current IEEE 802.16 standard, such as BS/RS spoofing. Additional measures are needed to ensure that each component in the network is a trusted...
Wireless mesh network (WMN) technology extends the service coverage by supporting multi-hop communication and enhances the network capacity by utilizing multi-radio and multichannel. The number of multiple channels is essential for the implementation and the efficiency of channel assignment. While the number of channels is not sufficient, channel assignment needs to consider the channel sharing at...
In a wireless mesh network (WMN), mesh routers (MRs) are interconnected by wireless links and form a wireless backbone to provide ubiquitous high-speed Internet connectivity for mobile clients (MCs). The wireless backbone is tightly integrated with the Internet by a special kind of nodes called as Internet gateways (IGWs). Even though the capacity of WMN can be improved by equipping the MRs with multiple...
Unlike ad hoc networks where traffic is randomly distributed among every pair of nodes, the traffic in wireless mesh networks (WMNs) is predominantly toward or from the Internet Gateways (IGWs)for Internet services. Due to this, interference and collision are more serious in the Mesh Router (MRs) closer to the IGWs and the Internet throughput of the network is limited by the number of orthogonal channels...
