Battery Power and Trust based Routing Strategy for MANET

Abstract

The communication in mobile ad-hoc networks (MANETs) is a multi-hop communication in which a source node communicates with a distant node using intermediate nodes in order to save the power. Thus the major activity in MANETs is to find a suitable route such that the delivery of the message can be done in an efficient manner. So, the route should be selected such that all the nodes in the path are trustworthy, non malicious and unselfish. However, misbehaving nodes may affect the performance of MANETs. Source sends a Route Request packet (RREQ) in order to find a path for data communication. In order to reply RREQ Route Reply Packet (RREP) are also transmitted by destination to source. In this dissertation, we begins with the format of RREPs which consists of six constraints such as source address, destination address, battery power of node, trust value of node, packet type and node-count. The aim of the proposal is to find out the path without any selfish node, i.e., the nodes whose energy and trust is low will not be the part of the route from source to destination. Protocol takes inputs from user and output parameters (such as suitability factor, average throughput and selfish node drop fraction) are recorded in output file known as trace file. After simulation, it can be concluded that path discovered after the use of this proposed protocol improves the performance of the network with respect to parameters throughput, suitability factor and selfish node drop fraction.
