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 derived taking into account the interference from other nodes. It is shown that while the effects of uncompensated intersymbol interference (ISI) can be quite detrimental, the network exhibits enough robustness against multiuser interference.
