Executive Summary

In this paper, the authors present a multicast protocol which builds upon a cluster based wireless network infrastructure. First, they introduce the network infrastructure which includes several innovative features such as: minimum change cluster formation; dynamic priority token access protocol, and; distributed hierarchical routing. Then, for this infrastructure they propose a multicast protocol which is inspired by the Core Based Tree approach developed for the internet. They show that the multicast protocol is robust to mobility, has low bandwidth overhead and latency, scales well with membership group size, and can be generalized to other wireless infrastructure.
