Research on the Design of the Effective Transmission SchedulingAlgorithm Based on the Factory Wireless Sensor Network

In order to make the sensing data in the monitoring equipment's sensor nodes reach to the monitoring center as soon as possible and deal with the equipment which has some problems, the network time delay should be guaranteed in the accessible Time Delay Bound. The paper mainly researches the transmission scheduling algorithm with the chain framework, which adopts the Token to do the transmission in the chain and then arranges the transmission order in each node for avoiding the occurrence of the collision and offering the guarantee of the time delay. The node order in each chain is the order of data packets which are transmitted by nodes, while the route of the data packet transmission is ac- cording to the shortest route in the Sink Tree for reducing the time delay.
