Review on Coverage and Connectivity in Underwater Wireless Sensor Networks

One of the current trends of the wireless communication is the underwater communication .The two most fundamental problems in underwater sensor network are sensing coverage and network connectivity. The coverage problem reflects how well a sensor network is tracked or monitored by sensors. An underwater wireless sensor networks is the emerging field that is having the challenges in each field such as the deployment of nodes, routing, floating movement of sensors etc. The characteristics of underwater wireless sensor networks are fundamentally different from that of terrestrial networks. In Underwater wireless sensor network each node monitor one target .For the connectivity of nodes use DFS (Depth first search) algorithm and for coverage use distributed coverage algorithm.
