Cooperative multihop communication for underwater acoustic networks
In this work, multi-hop cooperative schemes for underwater sensor networks are studied and shown to be highly energy efficient. Also, the signal model for a multipath channel is d...

User Cooperation Through Network Coding
Abstract-- Most user cooperation protocols work in a timesharing manner, where each user transmits its own message and relays for the other at different segments of a time slot. We...
