Routing in Ad Hoc Wireless Networks using Soft Computing techniques and performance evaluation using Hypernet simulator

Abstract

An ad-hoc network is a collection of wireless mobile hosts forming a temporary network without the aid of any established infrastructure or centralized administration. In such an environment, it may be necessary for one mobile host to enlist the aid of other hosts in forwarding a packet to its destination, due to the limited range of each mobile host’s wireless transmissions. Much effort has gone into mobile ad-hoc network (MANET) research over the past decade. Yet, even to- day, mobile ad-hoc networking is seen as a relatively new area of research. The reason for this can be traced to the fact that the maturity in truly understanding these networks is still alarmingly low and actual deployment of these networks rare. This paper presents a protocol for routing in ad hoc networks that uses soft computing techniques like neural networks, fuzzy logic and genetic algorithm. The simulation has been performed using hyper net simulator for various existing protocols like proactive routing , reactive routing, power aware routing protocol, hybrid routing . Our protocol uses soft computing techniques protocol for establishing the link between the nodes in minimum time. The results of our experimentation have been very satisfactory and we have achieved the goal of optimal route finding to a large extent. The simulation results are obtained using hypernet simulator and are also compared with the results obtained using NS-2 .
