Effects of Source and Destination Movement on MANET Performance Considering OLSR and AODV Protocols

In recent years, MANETs are continuing to attract the attention for their potential use in several fields such as military activities, rescue operations and time-critical applications. In this paper, we present the implementation and analysis of our implemented MANET testbed considering AODV and OLSR protocols for wireless multi-hop networking. We investigate the effect of mobility and topology changing in MANET. In this work, we consider four scenarios: Static, Source Moving, Destination Moving and Source-Destination Moving. We assess the performance of our testbed in terms of throughput, number of dropped packets and delay. From our experiments, we found that OLSR protocol has a better performance than AODV when both source and destination nodes are moving. AODV as a reactive protocol, is slower than OLSR when routes are changing quickly and continuously.
