Use of wireless technology increases rapidly in present days because of convenient use for its users. Wireless sensor network is one of the widely used wireless technologies. Although wireless sensor network has many advantages over other communication technologies, but still anguish from some limitations like limited battery power, control overheads, scalability, data aggregation, throughput etc. MAC layer is considered as most power consuming part over communication. Numerous MAC protocols had been designed to enhance the lifetime of wireless sensor network. In this paper, we have chosen a TDMA based MAC protocol for our proposed work. In our proposed work we try to improve existing work i.e. BEST-MAC protocol using artificial intelligence. We considered two performance parameters that are energy efficiency and throughput of wireless sensor network to improve the life span of WSN using optimal cluster head selection process. Our proposed work is implemented with MATLAB version R2012a and results are included in this paper. The results shows the energy is saved by 3.085% and throughput is improved by 51.26% in the proposed work as compared to BEST-MAC protocol.
