High-throughput, reliable multicast without "crying babies" in wireless mesh networks
There are two primary challenges to supportinghigh-throughput, reliable multicast in wireless mesh networks (WMNs). The first is no different from unicast: wireless links are inherently lossy due to varying channel conditions and interference. The second, known as the "crying baby" problem, is unique to multicast: the multicast source may have varying throughput to different multicast receivers, and hence trying to satisfy the reliability requirement for poorly connected receivers can potentially result in performance degradation for the rest of the receivers. In this paper, we propose Pacifier, a new high-throughput reliable multicast protocol. Pacifier seamlessly integrates four building blocks, namely, tree-based opportunistic routing, intra-flow network coding, source rate limiting, and roundrobin batching, to support high-throughput, reliable multicast routing in WMNs, while at the same time effectively addresses the "crying baby" problem.
