Abstract

There are two classes of routing protocols optimized for MANETs: proactive and reactive protocols. Due to the dynamic nature of MANETs where nodes frequently move, links break, and path reconstructions are required, the network efficiency is greatly affected by the performance of the routing protocol, which constructs the paths. The main challenge in MANETs is the limited batteries of the nodes. An efficient routing protocol uses this limited energy in a way that while it prolongs the network lifetime, the delivery rate remains high and the average delay is short. We present the conditions for an optimal routing protocol for MANETs by analyzing the energetic sustainability, delivery rate and average delay of the network. We used network simulator ns2 to model and evaluate the network performance for each protocol. We analyzed the protocols for five scenarios with increasing densities. The results showed that in a dense network, proactive protocols, particularly OLSR (Optimized Link State Routing Protocol), have better performance and in a low-density network, reactive protocols, particularly AODV (Ad Hoc On-Demand Distance Vector), have better performance. Depends on the application, the users can use these results to select the optimal protocol. As the second step, we are working on a hybrid protocol that eliminates the routing overhead of proactive protocols in low-density networks and the delay of reactive protocols in dense networks. A hybrid protocol purposefully distributes enough routing information sufficient for rerouting with a high rate and short delay. In this way, it improves the network performance and sustainability in both low and high densities. Keywords:
