Abstract:
Underwater Sensor Networks (UWSNs) are being deployed for range of applications like collection of oceanic data for research, military surveillance, disaster prevention, underwater exploration etc. Characteristics such as use of acoustic signal for communication, 3D deployment, and higher losses make routing in UWSNs different from terrestrial sensor networks. In this paper, we present a location aware routing algorithm based on routing factor (Rf); a function of distance and energy. In our proposed algorithm, forwarding node is selected by sender amongst its neighbors depending on their distance from destination node and residual energy. To consider energy with distance, Energy scale value (Es) is used as a scaling range. Priority packets are also used for quick delivery of packets. Simulation results show improved performance of our routing algorithm in terms of network lifetime and end to end delay.
