Study and Implementation of Multipath Routing Protocols in Wireless Sensor Network

Abstract

Designing efficient and reliable communication protocols for wireless sensor networks in monitoring applications is a challenging task, due to the uncertainty and dynamics of the environment. In this project, two routing protocols namely AODV routing protocol (a reactive protocol) and EESAA routing protocol have been compared. AODV being a reactive protocol it still uses characteristics of a proactive protocol. Routes in AODV are discovered and established and maintained only when and as long as needed. To ensure loop freedom sequence numbers, which are created and updated by each node itself, are used. These allow also the nodes to select the most recent route to a given destination node. Whereas in EESAA, minimize the energy consumption by using the concept of pairing. The algorithm makes many improvements on the way of dividing clusters, strategy of electing the cluster head and construction method of data relay path, the two aspects of inter-cluster energy balance and energy balance among the cluster are taken into account at the same time. The experiment is carried out using MATLAB environment. Simulation result shows that the proposed algorithms give better performances and reduces the energy consumption.
