Energy-efficient Communication in an Underwater Acoustic Sensor Network

Abstract

Energy efficiency is one of the major concerns in UWSNs due to limited energy budget of the underwater sensor nodes. In this paper, the solution of avoiding energy holes in UWSNs is discussed while taking in to consideration of the unique characteristics of the underwater channel.so here proposed Even Data Distribution scheme to tackle the energy holes created due to unbalanced energy consumption in UWSNs. Using this scheme, to balance the energy usage through the network provided that sensors can use multiple transmission range when they send or forward the periodically generated data. In this proposed scheme the sensor node can able to adjust their transmission range up to three possible levels. And also determine the set of possible next hops with the associated load weights that lead to a fair energy consumption among all under water sensor. Hence energy holes can be avoided and consequently the network lifetime is highly increased.
