摘要:

针对地理位置的无线传感器网络路由算法往往只注重地理信息的不足,提出了一种融合节点能量的多径路由算法。算法采用
地理位置和能量信息建立三维坐标系,根据邻居节点有效向前距离和剩余能量大小来计算下一跳的概率值,进行路由选择。
使能量消耗分散在有效向前推进距离较远的邻居节点之中,延长了网络生存时间,减小并推迟了路由“空洞”的出现。仿真
结果显示,区域内节点死亡数、节点存活数和路由“空洞”数等相对TPGF算法均有较大改善,验证了算法的有效性。

Abstract:

The wireless sensor network routing algorithm based on geographical position only focuses on the geographic
information. We propose a multi-path routing algorithm based on energy of nodes. We use geographic location
and energy to establish a 3D coordinate system and calculate the probability of the next hop according to the
effective forward distance and the energy of neighbor nodes. The energy consumption is scattered in the
neighbor nodes which are effective to move forward so the network survival time is prolonged. Routing holes
are reduced and delayed. Experimental results show that the number of dead nodes, surviving nodes and routing
holes are significantly improved in comparison with the two-phase geographic greedy forwarding (TPGF)
algorithm. The validity of the algorithm is verified.
