Multicast communication in “ad hoc” networks

This paper presents a simulation comparison of two unicast “ad-hoc” network routing protocols and proposes a multicast protocol extension, which is based on dynamic source routing (DSR). Our new multicast approach works sender oriented and spans a delivery tree by reusing inherent route information from DSR. Simulation results show that this protocol is efficient and outclasses in various performance measurements the well-known unicast solutions “TORA” and “DSR”
