Abstract

The aim of this study is to compare the performance of Optimized Link State Routing (OLSR), Ad hoc On-demand Distance Vector (AODV) and Greedy Perimeter Stateless Routing (GPSR) routing protocols with respect to network size and density. Each of these protocols represents the three categories of MANET routing protocols which are proactive, reactive and geographical routing protocol, respectively. The evaluation was done through simulation and the performance was measured in terms of throughput, average End-to-End (E2E) delay, Packet Delivery Fraction (PDF) and Normalized Routing Load (NRL). The results of the simulations show that the GPSR protocol is superior to OLSR and AODV in most cases. The results also show that throughput, end-to-end delay and packet delivery fraction are largely affected by the network size, while normalized routing load is largely affected by the number of nodes in the network.

Highlights

Mobile Ad hoc Network (MANET) is a type of network that does not require a fixed infrastructure (Conti and Giordano, 2014)
MANET routing protocols is categorized into 3 main groups: proactive, reactive and geographical routing
The objective of this study is to investigate the effect of network size and density on the performance of MANET routing protocols using simulation

Summary

Introduction

Mobile Ad hoc Network (MANET) is a type of network that does not require a fixed infrastructure (Conti and Giordano, 2014). Given a condition where a sender node is beyond the transmission range when data transmission is initiated, communication can still occur if there are hosts between the sending and receiving nodes that are willing to forward data packets to the receiver node (Elgohary et al, 2014) This is known as multi-hopping, a distinctive characteristic of MANET. Protocol geographical route scales is useful for large multi-hop wireless network topologies because the physical information of the nodes is tracked via using GPS or other types of positioning services. According to Son et al (2004), this protocol works by having each node forward a packet to the neighboring node nearest to the destination (Son et al, 2004) This is known as the greedy mechanism. The objective of this study is to investigate the effect of network size and density on the performance of MANET routing protocols using simulation
