Abstract: This study designs a MAC by using the hybrid TLBO-PSO algorithm for the Wireless Body Area Network (WBAN). The CSMA/CA based MAC computes the delay to transmit the data on channel by sensing the channel along with adding a random delay. The designed MAC uses the basic concept of CSMA/CA to sense the channel but the delay added to transmit the data is the optimized delay computed by the TLBO-PSO algorithm. The algorithm also, uses the low range sensor to reduce the specific absorption rate resulting less bad affect on human body due to sensor radiations. The performance of the algorithm has been compared with existing three state of art techniques, TDMA based MAC, Aloha based MAC, CSMA/CA based MAC optimized by PSO on different WBAN scenarios. The results clearly show the significance of designed technique.
