Angle Adjustment for Vertical and Diagonal Communication in Underwater Sensor

Underwater wireless sensor network has been an area of interest for few previous decades. UWSNs consists of tiny sensors responsible for monitoring different underwater events and transmit the collected data to sink node. In the harsh and continuously changing environment of water, gaining better communication and performance is a difficult task as compared to networks available on land because of different underwater characteristics such as end-to-end delays, node movement and energy constraints. In this paper a novel routing technique named angle adjustment for vertical and diagonal communication was proposed which don’t use any location information of nodes. It is also efficient in terms of energy and end-to-end delays. In this approach, the source node evaluates the flooding zone based on the angle by using the basic formula for forwarding the packet to the sink. After evaluating the flooding zone, the angles of each node are compared and the packet is sent to node closest to vertical line. The proposed approach is evaluated with the help of NS-2 with AquaSim. The results show better results performance in data delivery, end-to end delays and energy consumption than DBR.
