Performance Evaluation: MAODV (Tree-based) Vs. PUMA(Mesh-based) Multicast Protocols for MANETs

Abstract

To achieve better performance of multicast routing protocols for MANETs in various scenarios is still a contemporary issue for the researchers to explore. Distribution structure created as tree or mesh may cause pros and cons in these protocols. Among them MAODV which creates Tree based structure and PUMA creating Mesh based structure are famous routing protocols for MANETs. The research paper evaluate these protocols, and their performance is arbitrated by applying various stress conditions. These stress conditions are based on exponentially increasing the number of simultaneous listeners and join-leave sessions per node to evaluate the appropriate distribution structured protocol surviving and maintaining its performance. Increasing the join/leave sessions in different scenarios particularly assesses the strategy of distribution structure. Packet delivery ratio (PDR) is taken as a metric to compare the performance of above mentioned MAODV and PUMA multicast routing protocols.
