Reliable multicast protocol based on reputation mechanism in wireless multi-hop networks

To improve the reliability of the multicast tree and the efficiency of multicast, a multicast protocol based on reputation mechanism was proposed. The protocol took into account reputation value of the nodes in constructing the multicast tree, thus excluding the selfish nodes from it, making the multicast path comparably reliable. Simulation results show that proposed protocol can significantly improving the efficiency of multicast at a lower cost.
