针对无线传感器网络数据聚集查询的需求，提出了一种针对无线传感器网络网内聚集的多路径路由算法EOD。EOD算法综合考虑了节点剩余能量、偏移角度、节点间距离三个因素对无线传感器网络数据传输过程的能耗、时延的影响，在多路径结构的基础上，对传感器节点的所有的邻居节点进行综合评估，选择转发成本最小的几个邻居节点作为转发节点，从而在确保可靠性和性能的前提下最小化WSN能量消耗。仿真实验表明，适当地调整各影响因素的权值，EOD算法可以有效地延长网络生存期，减少数据包在网络中的时延，使整个传感器网络的节点剩余能量趋于均衡。

For the data aggregation query needs of wireless sensor networks, this paper proposes a novel multipath routing algorithm (EOD) to process in-network data aggregation in wireless sensor networks. EOD synthetically considers the influence, caused by the residual energy of node, offset angle and distance between nodes, on power consumption and transmission delay. On the basis of multi-path structure, EOD fully evaluates all its neighbor nodes for each aggregation node and selects the neighbor nodes with the minimal transmission cost as the transmission node in order to minimize energy con-sumption of the wireless sensor network in the premise of ensuring the reliability and performance. Simulation results show that EOD can effectively prolong the network lifetime, reduce latency in the network and make residual energy of nodes in the whole sensor network balance by adjusting the weights of each influence factor.
