Delay Tolerant Geographical Dynamic Routing Protocol for Under Water Wireless Sensor Networks

The underwater wireless sensor networks poses many challenges due to critical underwater environment such as large propagation delay and limited bandwidth capacity of acoustic channels. The sensor nodes under mobility causes the problem of delay, more energy consumption and undetermined propagation losses. In this paper we propose a routing protocol based on geographical dynamic routing (DTDRP) to address some of these problems. We focus on minimizing the delay and maximizing the throughput thereby increasing the energy efficiency. The simulations are carried out to analyze the performance of the proposed algorithm by comparing with the existing protocols in underwater environment conditions.
