| Abstract: | A new low-power wireless sensor network MAC protocol was proposed. In order to reduce the energy consumption of the net- work, the binary exponential backoff algorithm on the basis of the IEEE 802.15.4 MAC protocol was improved, and the fast back off mechanism and the adaptive adjustment competition window mechanism were introduced. Muhi-channel power control mechanism was adopted to reduce energy consumption. Simulation shows that the MAC protocol can achieve the desired effects. |
