In wireless adhoc network, routing protocol plays an important role establish and to maintain end-to-end communication path. Effects of propagation environment and mobility of the nodes have to be considered in the routing protocol. In this research, we investigated proactive and reactive routing protocol performance in a more realistic environment with dynamic network topology scenarios. We proposed a more realistic model scenario which includes Rician and Rayleigh multipath fading. Performance evaluation using the proposed model has been performed for two routing protocols, Dynamic Source Routing (DSR) as reactive routing protocol and a proactive routing protocol optimized Link State Routing (OLSR). Considering the dynamic nature of the wireless adhoc network architecture, we focus on network topology change scenarios by increasing number of nodes and behavior of the node. The results show that OLSR give more advantages of higher throughput and smaller end-to-end delay compare to DSR in Rician and Rayleigh environments due to multipoint replying (MPR) strategy. However, DSR have more efficient in packet routing control with smaller normalized routing load. For dynamic topology change in Rician and Rayleigh fading, OLSR performs more stable and can gain higher performance than DSR.
