中文摘要：
针对无线传感网络中,能量有效路径的数据传输可靠性较低和链路失效的问题,提出一种动态可调的基于路径可靠性估计的数据融合方法。该方法根据路径平均收包率、冗余变化粒度以及平均能耗,对路径可靠性估计曲线上的可靠突变点进行动态定位,监测人员能够对当前的路径可靠性进行实时估计;然后通过一种冗余传输的方法来提高整体的路径可靠性和平衡网络能耗。实测结果验证了该方法的有效性。
英文摘要：
In wireless sensor networks,data transmission with energy-effective path faces the problems of lower reliability and link failures.Considering these problems,an in-network data aggregation approach is proposed for energy efficient routing based on the estimation of path reliability.According to the average PRR,granularity of redundancy changing and average energy consumption rate,this method could dynamically lock the abrupt change point in path reliability curve,so that it makes possible for a user estimate the current path reliability in real-time.A redundant transmission approach is employed to improve path reliability and to balance the network energy consumption.The experiment result validates the proposed algorithms.
