Abstract: In Mobile Ad hoc Networks (MANETs), battery power is a limited resource and it is expected that battery technology is not likely to progress as fast as computing and communication technologies do. Hence, in order to lengthen the lifetime of batteries is an important issue which is supported by batteries only. But the existing power control techniques rarely consider the delay incurred in power estimation and connectivity of the network. Overhead problems are also caused by sending RTS packets. In order to solve the above problems, researchers propose to develop a power control MAC protocol for minimizing the power consumption and increasing the throughput in MANET. Initially, researchers assume that each node contains a neighbor set (NSET). Based upon the critical transmission range for connectivity, the nodes within the transmission range can be identified. Within the transmission range, the source node chooses the nodes with optimal initial transmission power value. These are stored in NSET to which the source can directly transmit the data with the selected optimal transmission power values. For the nodes beyond the transmission range, the power values of the intermediate nodes are also calculated and the source node sends data to the destination through nodes that has minimum transmission power value.
