Has the same problems as the traditional wireless LAN, wireless mesh networks (WMN) is anticipated to resolve the limitations and to significantly improve the performance of ad hoc network. In fact, differs from that of planning other wireless networks, such as cellular systems WLAN, design such a WMN to cover in a given region can be a non-trivial task. To solve the optimization problem of routing...
Wireless mesh networks (WMNs) have become a better alternative for extending wireless Local Area Networks (WLANs) to provide network coverage up to the furthest of far flung rural areas. This has been implemented by using a meshed backbone network interconnecting the mesh access points (MAPs) that manages each of the WLANs. The routing algorithms use the mesh backbone to establish inter-WLAN routes...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
Wireless mesh network (WMN) has become a popular access network architecture. But because of its multi-hop nature, co-channel interference and contention, the attainable capacity of a wireless node in a WMN is significantly less than the radio capacity. We propose a overlay architecture for a WMN, where a wireless-ring (WRing) is deployed over the regular mesh for carrying wireless mesh traffic only...
