In wireless ad hoc networks, collisions and congestion at some nodes cause degradation of network throughput. There have been some load‐aware routing protocols proposed for load distribution and balancing by detouring congested nodes. However, they are for unicast communication. This paper proposes a load‐aware protocol for the same purpose in multicast communication. The protocol has features to build a multicast tree with load distribution and balancing, and to reorganize the tree according to dynamic load changes. Simulation‐based preliminary experiments result in that the number of highly loaded members in a multicast tree was smaller with the proposed protocol than that with a conventional one.
