Magnetic Induction Based Modified Depth Based Routing for Underwater Wireless Sensor Networks

Magnetic induction has emerged as a new communication paradigm by addressing several disadvantages of previous communication ways in Underwater wireless sensor networks. Energy consumption and routing are critical issues in UWSN devices as the devices are battery powered and are expected to operate for a very long time and routing algorithms disagree with the modification in communication methodology. In this paper, we proposed a multi-hop energy consumption model and a variant of depth-based routing protocol for underwater sensor networks employing MI communication. Proposed energy consumption model defines energy consumption in terms of distance among coils and number of hops between sender and receiver coils. Modified Depth Based Routing uses depth, residual energy information in routing decision. Simulation results show that Modified depth based routing improves packet delivery ratio and end-to-end delay in comparison to Depth Based Routing.
