摘要
研究基于IEEE 802.15.4标准的GTS的请求和确定,建立单设备和多设备请求GTS的Petri网响应模型,并对实时通信的延迟进行估计和仿真。根据仿真结果,确定当满足一般实时性要求时,传感器网络规模应该满足的条件。其研究成果对于传感器网络在实时环境下的应用研究具有重要的参考价值。
This paper researches the request and locating Guaranteed Time Slot（GTS） of IEEE802.15.4,puts forward the Petri net model about the request and locating of GTS for a single device and multi - devices, estimats and simulats the delay of real- time communication. According to the simulation result,the condition of the sensor network meeting when the general real- time should be satisfied. The results of the paper have important reference values for research on application of sensor network under the real - time circumstance.
