中文摘要：
针对无线传感器网络数据聚合存在的数据时延增加与节省能耗这一矛盾,提出了一种综合考虑节点剩余能量与数据时延、支持QoS的分布式数据聚合策略,各个节点依据其他数据经由该节点转发的概率与能耗情况,自主地决定是否成为聚合节点,仿真结果表明,QoS算法在网络的生命周期,数据时延和抗毁性方面均优于经典的LEACH和PE-GASIS算法。
英文摘要：
Due to the contradiction between the increase of data delay and the reduction of energy consumption in data aggregation for wireless sensor networks,a distributed data aggregation strategy supporting QoS is proposed,which considers the residual energy on the node and data relay in this paper.Basing on probability that it forwarding the other data and residual energy,each node decides to be a aggregation node or not by itself.The simulation shows that the QoS algorithm is superior to classical LEACH and PEGASIS algorithms in the network life cycle,the data delay and invulnerability.
