无线传感网络中转发节点优化的多跳路由

Multi-hop routing optimized by forwarding nodes in wireless sensor network

为了进一步提高3维无线传感网络的数据传输效率,减少节点能耗,提出1种基于能效角度的路由(EEAR):从最优选择转发节点的角度构建路由,利用角度构建候选转发节点集;然后计算候选转发节点集内每个节点的权重值,该权重值融入节点剩余能量和距离信息,剩余能量更多、离信宿更近的节点权重更大,则成为转发节点的概率更高。实验结果表明,提出的EEAR路由能够降低能耗,并提高数据包传递率。

In order to further improve the data transmission efficiency and reduce the node energy consumption in three dimension wireless sensor networks,the paper proposed an energy efficient angle based routing(EEAR):the routing was constructed from the perspective of optimal forwarding nodes,and the angle was used to establish the candidate forwarding node set;then the weight value of each node in the candidate forwarding node set was calculated,which integrates the residual energy and distance information of the node to make the node with more residual energy and closer to the receiver greater weight,so as to obtain the higher probability of becoming a forwarding node.Experimental result showed that the proposed EEAR routing could reduce the energy consumption and improve the data packet transmission rate.
