A comparison of MAC protocols for wireless local networks based on battery power consumption

Energy efficiency is an important issue in mobile wireless networks since the battery life of mobile terminals is limited. Conservation of battery paver has been addressed using many techniques. This paper addresses energy efficiency in medium access control (MAC) protocols for wireless networks. The paper develops a framework to study the energy consumption gf a MAC protocol from the transceiver usage perspective. This framework is then applied to compare the performance of a set of protocols that includes IEEE 802.11, EC-MAC, PRMA, MDR-TDMA, and DQRUMA(a). The performance metrics considered are transmitter and receiver usage times far packet transmission and reception. The analysis here shows that protocols that aim to reduce the number of contentions perform better from a energy consumption perspective. The receiver usage rime, however fends to be higher for protocols that require the mobile to sense the medium before attempting transmission.
