Performance Evaluation of Multicast Trees in Adhoc Networks

An adhoc wireless network is a network composed of mobile hosts with no fixed infrastructure and no central administration. The main constraints in these networks are bandwidth limitation and unpredictable hosts mobility. In this context, one challenge is to propose multi-hop routes for multicast routing protocols. In this paper, we present a set of criteria adapted to the evaluation of multicast diffusion structures in adhoc networks. We also use these criteria to evaluate different tree construction algorithms and propose several comments for the design of an efficient multicast routing protocol.
