System Level Analysis of Cluster-tree Based Wireless Sensor Network Design
簇状树形无线传感器网络系统级设计分析

Cluster-tree based topology is wildly used in wireless sensor network applications. In order to target different applications using this kind topology, a system level analysis approach is needed for the flexible and efficient protocol design and deployment. Based on a TDMA industrial MAC protocol,a system level model was proposed to reveal the relationship between network parameters and application requirements on reliability, energy efficiency and delay. The large scale deployment and experiment on the factory real field showed that the approach could be useful for the adj ustment of protocol parameters and satisfy the application recauirements.
