Adaptive Reliable Efficient Multicasting Protocol for Mobile Ad Hoc Networks‪.‬

Abstract: The Adaptive Reliable Multicast Protocol (ARM) with intermediate node support is introduced to guarantee message delivery to all multicast receivers in mobile ad hoc environment. ARM distributes multicast message cache and retransmission tasks among intermediate nodes to offer a scalable reliable multicasting. Due to limited memory and node's mobility, ARM defines intermediate node as all nodes which overhear multicast messages. Thus it includes not only multicast traffic conveyors but also their neighbors and group members. Simulation results show that ARM has a packet delivery close to 100% and maintains a low bandwidth consumption facing to frequent topology change. This protocol is also stable as traffic load increasing. Keywords: Mobile Ad Hoc Networks, Adaptive Reliable Multicast
