Abstract
There are various challenges in underwater wireless communication such as limited bandwidth, limited energy of sensor nodes, node mobility, high error rate, and high propagation delay. The main problem in underwater wireless sensor networks has limited power of battery as underwater sensor nodes cannot get charged due to deficiency of solar energy. Another main issue is the reliability. In this paper, an approach is proposed for energy-efficient communication among sensor nodes based upon the energy efficiency, reliability, and throughput of sensor node in UWSN (Underwater wireless sensor networks). It uses two step methods. First, it uses a method to identify node called as head node from a cluster which is required for effective communication. This node is responsible for communication with other nodes and further it sends the sensed data to surface station. Second, it finds path between the head node and underwater sink calculated by using Euclidean distance.
