Different TCP Agents for Evaluating Performance of OLSR Routing Protocol in MANETS

Abstract

Transmission Control Protocol (TCP) is a transport layer protocol which uses three way handshake mechanisms for connection establishment. The research issue is to use TCP in MANETs for communication between source node and destination node. TCP has various agents, which are used for connection with source node or destination node. Seven agents for source and four agents for destination has been used in this research in order to evaluate the performance of OLSR routing protocol and to identify the behavior of OLSR over TCP's various agents by some performance metrics. The environment of this research is campus and the parameters for simulation are area size, packet size, simulation time etc in order to investigate the performance matrices such as sent rate, received rate and drop rate of data packets, packet delivery ratio, average end-to-end delay and average throughput by using NS-2.35 simulator. The results show that with all of the agents of the source node the performance of OLSR is better when the agent of the destination node is Agent/TCPSink/DelAck or Agent/TCPSink/Sack1/DelAck or Agent/TCPSink/Sack1.
