摘要
无线传感器网络是一种典型的资源受限系统,研究信道和时隙在内的资源分配方法,对提高网络性能保障服务质量具有重要意义。为解决智慧医疗系统中传感网络结构不固定,服务质量无法保障问题,构建了一种非平衡的簇树结构,采用可避免碰撞、保证传输时延的时分簇调度算法进行传输任务的分配,将资源分配结果在Tiny OS系统中进行实现,并采用CC2530平台进行验证。为便于修改数据流参数,使调度的结果更加直观,设计了图形用户界面。结果表明这种时分簇调度算法可以保证非平衡结构无线传感网络通信质量,为大规模簇树网络提供有效的服务保障。
As a typical resource constrained system,Wireless Sensor Network（WSN） can be significantly improved theperformance of guarantee quality of service（Qo S） by effective resource allocation,including channel and time slot. Butthe structure is not fixed in smart medical system,which can lead to the uncertainty service quality. A non-balanced clus-ter tree structure is present for overcoming the collision and uncertain delay,taking into account the allocation of traffic.The resource parameter is implemented in Tiny OS system,which be verified by CC2530 platform. And Graphical UserInterface is designed for modifying data flow parameters and inspecting scheduling results. The experimental resultsshow that this cluster tree scheduling algorithm can ensure the non-balanced structure of network quality,and providetheeffective serviceguaranteeforlarge-scalecluster tree network.
