Abstract
This paper focuses on the multicast routing in wireless mesh networks under the 802.11s standard. This standard defines the HWMP (hybrid mesh network protocol) as the protocol of the routing but only unicast and broadcast. Such the standard defines the multicast routing as a goal among several and that the HWMP don't handle multicast messages, this reason motivates us to think about a solution to make the HWMP able to handle multicast routing. We try to resolve the problem by using the bases of MAODV (Multicast Ad-hoc on-demand Distance Vector) protocol for the reason that the HWMP is inspired from AODV (Ad-hoc On-demand Distance Vector) and the MAODV is just an extension of the AODV. The result shows that the scalability of the routing using different number of nodes in the network is excellent. For the mobility it can be agreed since the routers in mesh topology is almost static. Whereas, the rate of message control generated is still very high. In all, the HWMP become able to handle up the multicast messages.
