Performance of 802.11b Mesh Network Under Channel Interference for Wireless Internet

This article shows the performance of wireless mesh networks under channel interference for wireless Internet. The wireless mesh networks are multihop networks of wireless-router platforms. The wireless routers are typically stationary, but the clients can be mobile. A mesh network can provide multihop communication paths between wireless clients, serving as a community network or as a broadband access network for the Internet. Though no routing protocols exist for wireless mesh networknetworks, the author has tried using AODV, which has been proved effective for wireless mesh networknetworks. Although research is being done in revisiting the MAC and routing protocols for wireless mesh networknetworks, one of the major problems faced in 802.11b mesh networks is channel interference. Based on the above facts, an attempt has been made to study the performance of the 802.11b mesh network under channel interference. The performance differentials are analyzed in terms of throughput, end-to-end delay, and MAC delay. The simulations are carried out in Opnet Version 11.5 simulator
