Multicasting of connectionless traffic in resource-limited ad hoc wireless networks

In this work we address the problem of multicasting connectionless (packet oriented) traffic in energy and transceiver-limited ad hoc wireless networks. We first investigate the novel trade-offs caused by connectionless traffic as opposed to session-oriented traffic. Then we develop a new multicasting heuristic that is based on a minimum incremental cost logic. We also discuss the medium access (multicast scheduling) issues and propose a multicast scheduling scheme that works together with the proposed multicasting algorithm. Simulation results show that considerable improvement in energy and delay performance can be obtained by the proposed algorithms when compared with the ones that are originally designed for session based traffic.
