Dynamic Periphery Multicast Routing Protocol
In this paper, the authors describe a new multicast routing protocol for mobile ad hoc wireless networks. The protocol establishes a source based mesh of nodes called with no static periphery or zone to distribute data for that source. The notion of zone or a flooding group is different the flooding group is created based on hop count distance metrics and distance constraints. Also the zone or flooding group is a source based mesh. The protocol aims to improve connectivity and data delivery amidst topology changes and node movement. It avoids the drawbacks of tree based protocols in ad hoc networks viz fragility against topology changes, non-optimal paths in the case of shared trees, tree partitions, frequent tree reconstruction etc.
