摘要： 传感器网络sink节点的过载拥塞是影响其应用性能的重要因素.在分析了传感器网络中sink节点的收包过程后,把sink节点的收包过程概括为无线网卡中断处理和数据处理两部分.根据二级串连排队网络的理论,建立了收包过程模型并对此模型进行了过载性能分析,提出了一种自适应包丢弃的过载控制方案,并在Micaz平台上进行测试,测试结果表明该方案能够较好地解决sink节点的过载拥塞问题.

Abstract: Overload congestion of sink nodes is an important influencing factor on the applications of wireless sensor network. Analyzing essentially the packet receiving process of sink nodes, the process can be divided into two parts: the wireless NIC interrupt processing and data processing. According to the theory of 2-level serial queueing network system, a model of packet receiving process is developed with the overload performance analyzed in detail for it. Then, an improved method-adaptive packet discarding scheme is proposed, and its performance has been tested through experiment on Micaz platform. The result indicated that it can solve well the congestion problem at sink node.
