Performance comparison of routing protocols in wireless sensor networks

Abstract

This paper aims to compare performance of some routing protocols for Wireless Sensor Networks(WSNs). A Wireless Sensor Networks (WSN) is a set of hundreds or thousands of micro sensor nodes that have capabilities of sensing, establishing wireless communication between each other and doing computational and processing operations. The efficiency of sensor networks strongly depends on the routing protocol used. Routing protocols are needed to send data between sensor nodes and the base station. In this paper, we analyzed three different types of routing protocols: Fisheye, LANMAR, LAR1. Sensor networks were simulated using Qualnet simulator. Several simulations were conducted to analyze the performance of these protocols on the basis of performance metrices such as hop count, throughput, end-to-end delay. © 2011 Springer-Verlag.
