文摘

A Self-Adaptive Low Power MAC protocol with carrier sensing for ad-hoc Wireless LANs (WLANs), which is capable of operating efficiently under bursty traffic is proposed in this letter. The protocol utilizes a Learning Automaton structure at each station of the WLAN. Each such structure uses the network feedback to select the mobile station that will transmit. A low-power mode is implemented in order to significantly reduce the energy consumption of the protocol. Simulation results reveal that the low power mode of the proposed protocol reduces the average energy consumption at the mobile stations by as much as 70%.
