A traffic adaptive asynchronous media access control protocol of wireless sensor networks
Song Ling, E. Chi · 2016
The events which are monitored in wireless sensor networks(WSNs) always happens randomly, so the network traffic is dynamic. This paper proposes a traffic adaptive asynchronous media access control(MAC) protocol of wireless sensor network (TAASMAC). TAASMAC gets the number of packets which are waiting to be sent in the queue, according to the number, TAASMAC can get the current information of network traffic, and changes the sleep time. The TAASMAC also solves the broadcasting problem in asynchronous MAC. This paper uses NS2 to validate the TAASMAC, and the results show that the TAASMAC gets lower energy consumption while in low network traffic condition, and gets lower delay while in high network traffic condition.
