摘要
为均衡无线传感网络中节点的能耗,延长网络寿命,提出远距离节点间数据中转传输的WSN路由算法。根据Stojmenovi的理论,节点间数据传输功率在一段距离内可取到较小值,在此段距离内,节点间直接发送数据,超出距离的节点间数据传输,通过选择中间节点转发的方式来传输,依此来选择最小能耗节点进行路由,实现节点能量均衡的目的。仿真结果表明,所提算法与AODV和GRP路由算法相比,节点的路由能耗得到了均衡,使网络寿命得到了延长。
To balance the energy consumption of nodes in wireless sensor networks?and prolong the network lifetime,a WSN routing algorithm was proposed for the transmission of data between remote nodes.The minimum energy routing was selected according to Stojmenovi^s theory,the data transmission power between nodes could get a minimum value in some distance.In this distance,the nodes sent data directly,and if the distance between two nodes was over this distance,the node transmitted the data through the intermediate nodes.The minimum energy node for routing was selected to achieve the purpose of energy balance of nodes.Simulation results show that compared with the AODV and GRP routing algorithm,the routing energy consumption of nodes is balanced and the network lifetime can be prolonged.
