In this paper, three famous MANET protocols have been simulated for four km2 working areas with changes of the same elements in types of robots like speed, pause time, number of nodes, and key parameters that show network optimization rate including PDR, Throughput, and End-To-End Delay by using GloMoSim software. | International Journal of Computer Networks and Communications Security VOL. 3, NO. 8, AUGUST 2015, 343–354 Available online at: E-ISSN 2308-9830 (Online) / ISSN 2410-0595 (Print) Performance Evaluation of MANET Protocols in Communications and Management of Robots in Simulation Modelling Hanieh Movahedi, Bsc.

In this paper, three famous MANET protocols have been simulated for four km2 working areas with changes of the same elements in types of robots like speed, pause time, number of nodes, and key parameters that show network optimization rate including PDR, Throughput, and End-To-End Delay by using GloMoSim software. In total, LAR protocol was recognized that has better performance than AODV and DSR, which could be used as one of the optimum protocols. Keywords: MANET, Glomosim; LAR, AODV, DSR, PDR. 1 INTRODUCTION Now days, it is almost impossible to imagine our world without robotic systems. It has influenced drastically different aspects of human life and we can see their footprints almost everywhere. Controlling robots or machines is one the most important issues which has been researched and investigated in robotic area. Wireless controlling and robotic communication has great advantages like better maneuverability, lower cost, and faster preparation in different area. Moreover, by using wireless facilities, a network of robots can be acted in performing the given missions as a team and by setting the wireless connection between any of robots to each other, very novel capabilities can be obtained, practically. The robots are often equipped with low-cost, low power, short-range wireless network interfaces, which only permit direct .
