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.

In our research paper, we display an overview of different mobility models in ad hoc wireless networks. We demonstrate that gathering movement happens much of the time in specially appointed networks, and present another mobility model that is exceptionally effective and optimal for MANETs i.e. Optimal and Effective Mobility Model (OEMM) to speak to the relationship among portable hosts. OEMM can be promptly connected to numerous current applications. In addition, by appropriate selection of parameters, OEMM can be utilized to model a few mobility models which were beforehand proposed. One of the primary topics of this paper is to explore the effect of the mobility model on the execution of a particular network protocol or application. To this end, we have connected our OEMM model to two distinctive network protocol situations, bunching and directing, and have assessed network execution under various mobility designs and for various protocol usage. Not surprisingly, the outcomes demonstrate that distinctive mobility designs influence the different protocols in various ways. Specifically, the positioning of steering calculations is affected by the decision of mobility design.

The idea of fuzzy logic is based close to the human reasoning and regular exercises. It presents predicates which are available in nature and like those either enormous or little. This hypothesis copies human brain science in the matter of how a man settles on the choice speedier. Fuzzy logic is a superset of ordinary (Boolean) logic that has been stretched out to deal with the idea of halfway truth-truth esteems between "totally obvious" and "totally false". It can be actualized in equipment, programming, or a mix of both. It can be incorporated with anything from little, hand-held items to vast modernized process control frameworks.
