Evaluation of Multicasting Algorithms in Manets

Abstract — Disaster relief, education, and military are common situations where mobile nodes need to communicate in areas without any preexisting infrastructure. In these situations, MANETs (Mobile Ad-Hoc Networks) are used. When these nodes need one-to-many or many-to-many communication then multicasting is employed. Two of the best multicast protocols, MAODV (Multicast Ad-hoc On-demand Distance Vector Routing Protocol) and ODMRP (On Demand Multicast Routing Protocol), are compared. The performance measures to be evaluated are the PDR (Packet Delivery Ratio) and the Latency. Previous studies evaluate these algorithms with respect to the network traffic and the node speed. This study evaluates these algorithms with respect to the network traffic, the node speed, as well as the area and the antenna range for different simulation scenarios. MAODV performs better for high traffic. ODMRP performs better for large areas and high node speeds and poorer for small antenna ranges.
