Performance evaluation of a proactive link quality based uni- and multicast routing protocol for MANETs

Several proposals have been made to achieve efficient routing of unicast and multicast data in wireless mobile ad hoc networks. This paper evaluates a new approach to use link layer parameters to determine a link quality value for route calculation, especially for multicast data dissemination. Simulation results suggest that a shortest path metric is rarely the best choice. Instead, a signal strength based metric yields better results than other common protocols.
