| 摘 要： | 针对机会路由中候选节点数量过多的问题,提出一种基于距离的候选节点数量估计方法(DBNCE)。该方法根据当前节点到目的节点的距离,结合网络密度、当前节点邻居节点的数量等因素,为参与数据包转发的每个节点设置相应数量的候选节点。仿真结果表明,在机会路由中应用该方法,能够在保证数据传输成功率的基础上,有效地减少网络中候选节点的数量,从而提升网络的性能。

| Abstract: | Because the number of candidate nodes in opportunistic routing is too large,this paper proposed an estimation method of the number of candidate nodes based on distance (DBNCE).This method is used to set the number of candidate nodes for each node,which participates in forwarding data package according to the distance between the current node and the destination node,combining with network density and the number of neighbor nodes in current node.Simulation results show that using DBNCE in opportunistic routing will reduce the number of candidate nodes effectively while guarantee the success rate of data transmission,and improve the performance of the network. |

| Keywords: | Opportunistic routing Expected number of transmissions Candidate nodes Mean number of candidate nodes |
