摘要
提出针对无线传感器网络分层结构的一种数据可靠传输算法。采用综合节点剩余能量、缓冲区可用率、信道错误率3因素的可靠路径与备选可靠路径策略,依据缓冲区空闲情况进行预拥塞节点检测,进行路径前后疏导缓解拥塞。对簇头节点和非簇头节点的失效进行分类处理。仿真结果证明,该算法可提高数据传输的可靠性。
This paper proposes a reliable data transport algorithm for cluster structure in Wireless Sensor Network（WSN）. it includes： the choice of reliable routing and candidate routing considering residual node energy, buffer usability and channel error ratio, the detection of pre-congestion according to the spare space of a node buffer and the following catabatic methods, category handling the failure of cluster node or others. Simulation result shows that the algorithm improves the reliability of data transport.
