IEEE 802.11 is the basic standard for wireless networks in ad hoc mode. Wireless terminals are generally connected by batteries which provide limited transmission power and limited amount of energy. In this paper, the authors design a new MAC protocol algorithm for better spatial reuse, better throughput and a smaller packet loss. It can be achieved by adjusting power if the number of neighbors increases. It has achieved with power adjustments by calculating number of neighbors in the one hop neighborhood. Existing IEEE standards and other related works are compared with their work and it concludes the proposed paper is more adaptable.
