Logical sub-region with sink mobility for throughput maximization and energy consumption minimization in rectangular UWSNs

Abstract

Due to the limited battery power of sensor nodes, design of underwater wireless sensor networks (UWSNs) is very difficult. Information is not gained efficiently through sensor nodes in aquatic environment and energy consumption is also the major problem in UWSNs. We proposed logical sub-region with sink mobility for throughput maximization and energy consumption minimization in rectangular UWSNs (LSSR). Sensor nodes are randomly deployed in the network field. Two mobile sinks are moving strategically in the network field and gather data from their respective nodes and cover the maximum area of the network field. LSSR performs better in terms of network lifetime, throughput and residual energy as shown in the simulation results.
