A Trust based Reliable Routing Scheme for Wireless Mesh Networks

Wireless mobile is a utility tool for communication engineering. Mobility is one of the important characteristics. Due to mobility of nodes in wireless mesh networks, the shortest route is not necessarily the best path. For ensuring the stability of routing path, it is necessary to find out the path that endures a longer time. In this paper based on fuzzy logic, we have proposed a reliable routing scheme to achieve a more reliable route in wireless mesh networks. In this proposed scheme for each node in wireless mesh network, we have to determine three parameters, trust value mobility and battery power, to calculate the lifetime of routes. Each node in network during route discovery, inserts its trust value, battery power and mobility in route request packet. At the destination, by using fuzzy logic mechanism, a new parameter called “reliability value ” is generated from inputs trust value, battery power and mobility of each route. The route having more reliability value is selected as a stable route from source to destination. In this paper, we understand the various routing problems related to battery power, node‟s trust value and mobility of the node in the wireless network
