Wireless ad-hoc networking involves point to point communication in a network. To achieve an energy efficient communication wireless network is a challenging task. In this thesis, we propose a new modified power control MAC protocol which allows several source nodes to transmit data packets to a single destination in a round-robin fashion. The proposed idea is to use both IEEE 802.11 Power Saving Mechanism (PSM) and power control mechanism in wireless ad hoc networks. The power saving mechanism uses some control messages known as Announcement traffic indication message(ATIM). These control messages help the node to sleep or awake. Now, in this case, these control messages carry additional transmission power information, and these control messages are transmitted with maximum transmission power set by transmitting station. With the help of these ATIM packets, we can calculate the minimum required power to transmit the DATA and ACK packet. These data packets are transmitted in the data window. To allow several nodes to communicate with the destination by adding some delay to the backoff timer. This delay keeps on changing for every ATIM interval. The Simulation results of the proposed protocol show the advantages regarding the aggregate throughput and energy efficiency.
