Abstract

AbstractIn mobile Ad-hoc networks (MANETs) and Vehicle Ad-hoc networks (VANETs) various reactive and proactive protocols may be used for the transmission of packets from one node to another. Amongst all routing protocols, Optimized Link State Routing (OLSR) protocol is the most prominent and widely used protocol for MANETs. This paper presents the performance evaluation of OLSR protocol for TCP and UDP traffic patterns by (This work was partly supported by the NSFC under grant No. 61271246.) varying parameters like node density, node speed and pause time. Under different network scenarios, the performance of OLSR has been assessed in terms of the most widely used performance metrics, such as packet loss, end-to-end delay and throughput. The results prove that TCP performs considerably well in terms of throughput, end to end delay and packet loss in different node density and mobility scenarios, while considering pause time UDP turns out to be a better choice.
