This paper, proposes a new multicast routing protocol for mobile ad hoc networks that handles the congestion to improve the Quality of routing service. Part of the proposed protocol introduced a MAC layer level solution called Group Level Multicasting (GLM) that effectively handles the multicasting at one hop level mesh or tree. The proposed model controls the congestion in hierarchical order to minimize the resource utilization. Limited bandwidth and a high degree of mobility require that routing protocols for ad hoc networks be adaptive, trouble-free, and energy saving. This paper proposed a new Hierarchical Outflow Load-balancing Multicast Routing Protocol (OLMRP) for Ad-hoc networks, which handles congestion state.
