In order to make devices fast,accurate access network,and also to void collision which causes the network delay,resulting in large network bandwidth and power waste,this paper proposes a scheduling MAC layer protocol based on industry wireless sensor network.The adaptive scheduling method improves the WIA-PA super frame structure,during the period of devices access to the network,the network manager will adaptively adjust the length of each stage in frame structure,according to the real-time changes of dada throughput in the network,allocate communication resources reasonably.Tests show that this method not only avoids the waste of bandwidth,but also saves energy consumption,and has great practical value.
