Energy Balanced Load Distribution Through Energy Gradation in UWSNs
Underwater wireless sensor networks (UWSNs) find applications in various aspect of life like the tsunami and earthquake monitoring, pollution monitoring, ocean surveillance for defense strategies, seismic monitoring, equipment monitoring etc. The sensor node consumes more energy and load distribution suffer from imbalance at long distance. In this paper, we present an energy balanced load distribution through energy gradation (EBLOAD-EG) technique to minimize the energy consumption in direct transmission. The proposed scheme aims to balance the load distribution among different coronas of network field. In this scheme, the numbers of sensor nodes are uniformly deployed in a circular network field and the sink is located at the center of network field. In EBLOAD-EG, the accumulated data is partitioned into data fractions like small, medium and large. Simulation results show that our scheme outperforms the existing scheme in terms of energy efficiency, balanced load distribution, stability period and network lifetime.
