AMOMQ: Ad-Hoc Mesh-Based On-demand Multicast Routing Protocol with Quality of Service Support

In this paper we focus on one critical issue in mobile ad hoc networks that is multicast routing and propose a mesh based "on demand" multicast routing protocol for ad-hoc networks with QoS (quality of service) support. The proposed scheme has four key features: (a) it is based on the forwarding group concept (i.e., a subset of nodes is in charge of forwarding the multicast packets); (b) it dynamically refreshes the forwarding group members using a procedure similar to on demand routing;(c) it significantly reduces control overhead, and make the scalability of multicast routing protocol possible in mobile ad hoc networks by consolidation of control packets;(d) it support QoS routing using good estimation of available and required bandwidth, and reserving required bandwidth on the end to end active routes in multicast mode.
