Reliable and energy efficient cluster-based architecture for underwater wireless sensor networks

Underwater wireless sensor network (UWSN) provides a promising solution for discovering the aqueous environment efficiently which operates under many important constraints. At one side, these environments are not sufficient in case of energy efficiency and reliability. So in our paper we propose to develop a reliable and energy efficient cluster-based architecture for UWSN. Here the nodes cluster themselves and forms a cluster head. Next by deploying the courier nodes in the network data is aggregated from the CH. They also enable an intercluster communication to forward the sensed data. This increases the lifetime and the delay is less with the reduced buffer overflow problem.
