摘要
无线传感器网络的实时性是当前研究的热点。本文讨论了无线传感器网络的时延组成,利用排队论的相关理论建立了相应的数学模型,并在此基础上研究和计算了簇头节点内的信息时延,得到相应的结果。通过仿真验证了分组在系统中的逗留时间和系统中平均分组的个数都与分组长度无关等相关结论,为设计实时系统与选取相应的参数提供了一定的依据。
The real- time performance of wireless sensor networks has become research focus currently. This paper discussed the composition of wireless sensor network delay, and made use of the queuing theory to establish the corresponding mathematical models. Based upon this, the cluster head information transmission delay has been analyzed and calculated. Simulations proved that the length of the packet does not affect the average time of the packet that remained in the system and the average of the number of the packet in the system, etc. These results are useful for designing future real - time network system and selecting appropriate parameters.
