    Abstract
  • A WSNs-based real-time monitoring system was built in view of the application in hazardous materials transportation monitoring.MAC layer protocol and physical layer transmission time sequence of the monitoring system were improved and optimized.Priority supported GDCF algorithm was introduced after improving the original BEB algorithm of MAC layer.Effectiveness analysis was made for the RTS/CTS mechanism of MAC layer.Sleep mode was introduced for energy saving.Time sequence was optimized to reduce data transmission time and collision probability in physical layer data transmission.Practical test was made by IRIS node platform installing on an engineering automobile.Test result shows that the drop rate using improved backoff algorithm has no significant change with the increase of network node number.The drop rate without RTS/CTS mechanism reduces from the original about 20% to less than 6% when the giving sampling interval time is 50 ms, and 95% energy is saved in every working period.Design goal is achieved in improved time sequence of wireless data transmission, and the performance requirements in real-time monitoring system of WSNs are satisfied in practical application.
