| 摘 要： | 针对实际应用中无线传感器网络多区域分布、任务多元化的特点，为解决簇间通信的相互干扰，提出一种改进的FDMA/TDMA混合机制的无线传感器网络。簇间采用FDMA避免干扰，簇内节点采用TDMA实现睡眠调度。此外，在TDMA机制中分配监测时隙，如有突发情况，簇内节点可通过CSMA竞争与簇头节点实现通信，以此增加上报的公平性。对网络系统进行了工程实现验证，测试证明达到预期效果。

| Abstract: | For the characters of WSNs that distribute in various areas and have multiple missions, to solve the problem about the interference in the communication between clusters, this paper design a WSN structure based on the hybrid access technology with FDMA and TDMA. Among different clusters, a FDMA mechanism is adopted tu avoid interference, In clusters, nodes adopt TDMA to communicate with root node. Further more, system design a time slot for apperceiving based on the TDMA mechanism. In the time slot, nodes compete the channel through CSMA for event occurring. Project realization is also completed and expected indexes is achieved. |
