DSAB: Dual sink approach in WBANs

Abstract

The introduction of WBANs is a revolutionary step in health services field which plays a significant role in psychological, medical and also in applications that are non-medical. Different proposed routing protocols work in WBAN for performance enhancement, mainly focusing on network lifetime, throughput, efficiency, energy and delay. This paper presents DSAB routing protocol which is a reliable, and energy efficient routing protocol which enhances the network life-time through dual sink approach. These existing protocol and routing protocol names are compared as ATTEMPT and LAEEBA. A mathematical formulation is used for the forwarder node selection which can be calculated by considering the distance of node from sink, transmission power and residual energy. Performance of DSAB is 55% and 22% more productive than ATTEMPT and LAEEBA in throughput. Simulation results bring forward that DSAB stability period is greater than ATTEMPT and LAEEBA with least delay. The parameter of energy in DSAB is better but not better than ATTEMPT and LAEEBA, because of RSSI utility which processes and utilizes more energy.
