Abstract—In this paper, we propose a new power control algorithm for Mobile Ad hoc Network (MANET). The suggested algorithm is a Link Expiration Time Aware Distributed Power management algorithm, (LETPOW). Our main aim is to periodically check Connectivity, Transmission power, Interference level, Routing overhead and Node Mobility in MANET. We deliver a modified time-varying signal-to-interference-noise ratio (SINR) formula. The proposed algorithm considers additional parameters such as link expiration time, continuous time interval and the total number of scheduled slots compared to the existing Distributed Power management algorithm (DISPOW) in distributing the power. The algorithm noticeably enhances the performance of the system and improves average power and thermal noise of network's nodes for a certain situation by almost 0.05Watt and -5dBm, respectively.
