WSN中流量自适应的超低功耗MAC协议
Traffic-aware Adaptive MAC Protocol with Ultra-low Power for WSN
摘要
Abstract
In order to reduce the power consumption of the sensor nodes in WSN,when data is being transmitted or received,the wireless communication module of the nodes are supposed to start operation to send the data or listen to the channel,otherwise it enters a sleep mode. However,the biggest problem is that the sensor nodes are unable to receive data when being in the sleep mode. Without a better protocol designed,data will be failed to be received since the nodes are in sleep mode,and thus the entire network performance is re-duced. For this problem,a new traffic-aware adaptive MAC protocols with ultra-low power for WSN is proposed. In the designed MAC protocol,the sleeping time and wake-up time in real time of the nodes are scheduled based on the network traffic. If network traffic is low,it enters the phase of non-scheduling or else the phase of scheduling. In addition to the advantages of synchronous network and asyn-chronous network,the algorithm is further improved in this designed MAC protocol. Compared with the existing traditional MAC proto-cols,the power consumption and the delay of the sensor network is reduced greatly with the designed MAC protocol.关键词
