ABSTRACT

Abstract Wireless body area network (WBAN) is growing enormously with the technical development of the internet of things (IOT). On body WBAN is one of the types in which sensors are located on the body of patient. Cooperative techniques are useful in mitigating the fading effect and improving the quality of the transmitted signal. In the current work, a mathematical model considering cooperative CM3A operating at ultra-wide band (UWB) (3.1–10.6 GHz) has been devised. A comparative performance analysis of received power and critical parameters like SNR, outage probability, probability of error, and the packet error rate has been carried out for cooperative and noncooperative scenarios. An objective function has been formulated to optimize link quality parameters using a particle swarm optimization algorithm (PSO). Simulation results obtained reveals that performance of considered cooperative WBAN is better in comparison to non- cooperative WBAN. Further optimization improves the outage probability of cooperative WBAN by approximately 30 % and energy consumption is reduced by approx.5 %. Cooperative approach is beneficial for considered WBAN scenario.
