Transmit power control is a prototypical example of a cross-layer design problem. Cross-layer design problem affecting all layers of the protocol stack from physical to transport, and affecting several key performance measures, including throughput, delay and energy consumption. It has some basic principles for power control is to increase the network capacity, reducing the transmit power level reduces the average contention of Medium Access Control (MAC) layer. It presents some protocols such as COMmon POWer (COMPOW), CLUSTER POWer (CLUSTERPOW) and MINimum POWer (MINPOW) which attempts to achieve several design objectives and perform several optimizations. The COMPOW protocol attempts to increase network capacity by choosing the common power level throughout the network duration. The CLUSTERPOW protocol provides joint solution to the power control, clustering and routing problem to maximize network capacity. The MINPOW, which globally optimizes the total energy consumption. In this paper we propose LOAD POWer (LOADPOW) power control protocol which adapts the transmit power according to the network load, avoids interference with traffic. We also perform the simulation of LOAD POWer with respect to throughput, energy consumption and delay and show that our protocol gives better performance than other protocol.
