Relative Performance Analysis of Proactive Routing Protocols in Wireless Ad hoc Networks using Varying Node Density

Abstract

A Wireless Ad hoc Networks consists of mobile platforms (e.g., a router with multiple hosts and wireless communications devices) here in simply referred to as "nodes" which are free to move about arbitrarily; thus, the network topology which is typically multi-hop may change randomly and rapidly at unpredictable times, and may consist of both bidirectional and unidirectional links. So that the development of dynamic routing protocols that can efficiently find routes between two communications nodes when nodes are mobile is very challenging task. To accomplish this, a number of ad hoc routing protocols had been proposed and implemented. Performance evolution of the protocols is the key step before selecting a particular protocol. In this paper, the performance of Optimized Link State Routing (OLSR) and Source Tree Adaptive Routing (STAR) protocol has been compared with respect tp varying node density using Qualnet 5.0.2 simulator. The average jitter, end-to-end delay, throughput, First Packet Receive (FPR), Last Packet Receive (LPR), Total Bytes Receive (TBR), and Total Packet Receive (TPR) are the common measures used for the comparison of the performance of above protocols. The experimental results show that overall performance of OLSR routing protocol is better than STAR routing protocol as increase the node density in a particular area.
