Energy efficient opportunistic routing algorithm for underwater sensor network: A review

Unique characteristic of underwater environments is challenging for wireless sensor network protocol. Opportunistic routing protocol is the most promising routing method to encounter the challenges. This paper will review three main algorithms; forwarding set selection and forwarding set ranking algorithms to handle FSR problem, void handling algorithm to handle the communication void (CV) problem, and overhear and suppression algorithm to deal with duplicate forwarding suppression (DFS) problem. The importance of the review is that it will direct the study to energy efficient pressure-based opportunistic routing algorithm for underwater wireless sensor network (UWSN).
