Secure High-Throughput Multicast Routing in Wireless Mesh Networks
... In a typical high-throughput multicast protocol, nodes periodically send probes to their neighbors to measure the quality of their adjacent links. During route discovery, a node estimates the cost of the path by combining its own measured metric of adjacent links with the path cost accumulated on th ...
