摘　　要：针对Gossiping协议中存在信息重叠、没有考虑到节点能量利用率和网络传输安全等问题,根据图论中Prims或者Kruskal算法来生成最小生成树的思想,在改进的最小生成树算法前提下,提出了一种传感器网络能量高效的安全路由(EESR)方案,引入了节点的可信度和能量值来作为图中边的权值,充分地考虑到能量的利用,同时防止了恶意节点篡改、丢弃数据包。实验结果表明:该方法提高了网络能量利用率,降低了网络丢包率,延长了无线传感器网络的生命周期。In order to solve the problems of information overlap,and without consideration on node-energy utilization rate and network transmission security in Gossiping protocol of wireless sensor networks,according to idea of minimum spanning tree idea is generated,by Prim or Kruskal algorithms of graph theory,a scheme of energy-efficient secure routing（EESR）of wireless sensor networks is proposed based on improved minimum spanning tree algorithm.It not only makes full use of the energy but also prevents malicious nodes from tampering or loss of datapacket by introducing reliability and energy value as weight values of sides.The experimental result shows that the proposed EESR algorithm improves the efficiency of network energy,reduces the loss rate of network packets and extends the life cycle of wireless sensor networks.
