“…Thus, instead of globally defining a uniform transmission range that keeps the network connected, wireless networks should adjust transmission ranges on each link. The power control problem in sensor networks is that of choosing the transmit power for each packet in a distributed fashion at each node [3]. The problem is complex since the choice of the power level fundamentally affects many aspects of the operation of the network.…”

To design energy efficient Medium Access Control (MAC) protocol for maximizing the network lifetime in Wireless Sensor Network (WSN), is evolving as a challenging portal in research area. The overall radio energy inherently depends on network workload as well as the radio characteristics. Therefore, we have proposed a Dynamic Power Control MAC (DPCMAC) protocol which supports variable power level transmission of packets according to data rate of sources. Our novel approach minimizes the aggregate energy consumption in all power states according to the network traffic. Moreover in our protocol, we calculate the desired power level for the transmission of packets for two types of scenarios: low and high network workload. The protocol is simulated for the variable size of networks and its performance is analyzed on the basis of success rate and energy consumption. The simulation results show that our protocol outperforms the existing Sensor MAC (SMAC) protocol.
