INTRODUCING A FAULT TOLERANT ROUTING PROTOCOL BASED ON FUZZY LOGIC IN WIRELESS SENSOR NETWORKS

Although routing is one of the key network issues, the challenges facing WSN makes the subject even more demanding. In this study, we propose a novel fault tolerant routing protocol in wireless sensor networks using fuzzy logic. We approach the problem by breaking it down intotwo parts. The first sub problem is designing a routing module and the second one retrofitting the designed module in a way that answering to these two sub problems leads to the final solution ofthe main problem. To deal with the first stage, by using fuzzy logic, we design a routing module;then for the second stage, the module enters fault tolerant routing in order that it be tolerant against routing faults. In this study, the term network failure is figuratively equal to node failure .
