A Reliable routing algorithm for Mobile Adhoc Networks based on fuzzy logic

By growing the use of real-time application on mobile devices, there is a constant challenge to provide reliable and high quality routing algorithm among these devices . In this paper, we propose a reliable routing algorithm based on fuzzy-logic (RRAF) for finding a reliable path in Mobile Ad Hoc Networks. In this scheme for each node we determine two parameters , trust value and energy value, to calculate the lifetime of routes . Every node along route discovery , records its trust value and energy capacity in RREQ packet. In the destination with the aid of fuzzy logic ,a new parameter is generated from inputs trust value and energy value of each route which is called "Reliability Value". The path with more reliability value is selected as a stable route from source to destination .Simulation results show that RRAF has significant reliability improvement in comparision with AODV.
