Abstract: “Wireless sensor network (WSN), is a distributed network of sensor nodes which performs critical tasks in many applications. The efficiency of WSN strongly depends upon the routing protocol used. The routing protocols developed for these networks need to exhibit good performance. To create a better understanding of the performance of various existing routing protocols it is very important to analyze their performances in detail. In this paper we have analyzed four different types of routing protocols: the AODV, DSDV, DSR, and AOMDV using NS-2 and compared in terms of throughput and normalized routing overhead (NROH), by varying pause time, maximum speed and rate. They also compared with IEEE802.11 and IEEE802.15.4. On comparison, the throughput of DSDV of IEEE802.11 and NROH of DSDV of IEEE802.15.4 are observed to be better.”
