Current multicast protocols in mobile ad hoc networks as dynamic movement of group members can cause the frequent tree reconfiguration with excessive channel overhead and loss of datagrams, the authors present a protocol for improving data delivery patterns in wireless adhoc networks using co-ordinate schemes. The proposed location-based multicast algorithm limit the forwarding space for a multicast packet to the so-called forwarding zone. Simulation results showed that their efforts will result into lower message delivery overhead with the potential for achieving accuracy of multicast delivery comparable with multicast flooding.
