Performance Comparison on Trust Based Power Aware Reliable On Demand Routing Protocol in Mobile Ad Hoc Networks

Abstract

A mobile ad hoc network (MANET) is a collection of mobile wireless nodes, which communicate to each other without any centralized administration. Trust and Power consumption is the most challenging task in routing protocol design for Mobile ad hoc networks (MANETs), since the highly dynamic nature of MANET coupled with limited bandwidth and battery power imposes severe restrictions on routing protocols especially on achieving the routing. Furthermore replacing and recharging batteries and making nodes co-operative are often impossible in significant environments. In this paper, we effort to study the performance of three on- demand routing protocols (AODV, DSR, DYMO) in terms of number of hop counts, number of routes selected, number of RREQ packets, number of RREP packets and power consumption in transmit, received and ideal modes. During route discovery, nodes are more trust to find reliable route for communication and utilizing maximum energy capacity for selection of route. Route based selection of nodes called 'Reliability'. Route request from the source is accepted by a node only if its reliability is high. Otherwise, the route request is discarded. This approach forms a reliable route from source to destination thus increasing network life time, improving power utilization and decreasing number of packet loss during transmission. To solve the above problem here we describe the three on demand routing and it is simulated using QualNet 5.0 simulator.
