MZR: a multicast protocol for mobile ad hoc networks

Abstract

This paper proposes a new multicast protocol for mobile ad hoc networks, called the multicast routing protocol based on zone routing (MZR). MZR is a source-initiated on-demand protocol, in which a multicast delivery tree is created using a concept called the zone routing mechanism. It is a source tree based protocol and does not depend on any underlying unicast protocol. The protocol's reaction to topological changes can be restricted to a node's neighborhood instead of propagating it throughout the network. A detailed simulation and performance analysis of MZR is presented.
