As for Ad Hoc networks is a method which using power control technology to improve the network energy consumption, with the situation of effectively reduce energy consumption but seriously decline of network throughput on the basis of power control algorithm. This paper presents a kind of distributed transmission power control MAC protocol (DTPMP) based on signal to noise ratio (SNR). The simulation results showed that mate lower node energy consumption in the first mate, while maintaining higher throughput performance of the network.
