Abstract: A mobile ad hoc network (MANET) protocol is affected by various environmental factors like mobility and fading, which depreciate the performance of the protocol. Though there is a commendable amount of work with different MANET protocol comparisons, seldom has there been a comparative study based on realistic simulation scenarios in order to examine the effects of network density, mobility and fading. Hence, this paper outlines a comparative study on the performance of three extensively employed reactive MANET protocols – AODV, DSR and DYMOUM. They are simulated in an environment effected by the three parameters and then thoroughly evaluated through a numerical study. The paper results in providing design considerations for the developing speed-aware routing protocol (SARP).
