Energy-efficiency optimization and the comparative performance analysis for Wireless Body Area Networks (WBANs)

This paper examines the energy efficiency of a non-cooperative and cooperative On-body Wireless Body Area Network (WBAN) and link reliability in a cooperative WBAN using IEEE 802.15.6 based CM3A channel model. The proposed energy optimization framework is based on Whale Optimization Algorithm (WOA) and Particle Swarm Optimization (PSO) techniques. For the optimized code rate, obtained results illustrate that WOA gives 44.7%. and 43.4% better results for the non-cooperative and cooperative cases respectively than the PSO. The link reliability has been investigated by observing the effect of the fading parameter (m) on the outage probability over the Nakagami m fading channel. The obtained results reveal how the fading parameter (m) affected the likelihood of an outage.
