DRADS: depth and reliability aware delay sensitive cooperative routing for underwater wireless sensor networks

In this paper, depth and reliability aware delay sensitive (DRADS), interference aware DRADS (iDRADS) and cooperative iDRADS (Co-iDRADS) routing protocols are proposed for maximizing network good-put while minimizing end-to-end delay. We have introduced a new metric called depth threshold to minimize the number of hops between source and destination while ensuring successful packet delivery. Our interference aware and co-operative routing based algorithms select the best relay node at each hop. Extensive simulation results validate that the proposed routing techniques perform better than the selected existing ones in terms of good-put and energy cost of the network.
