摘要: 以期望传输时延为度量指标,提出了传输速率感知的机会路由候选路由节点选择和排序算法。分解机会路由为节点到其候选路由节点集的anycast传输和候选路由节点集到目的节点的剩余机会路由传输,迭代计算节点的机会路由最小期望传输时延,根据最小期望传输时延选择和排序候选路由节点。模拟实验结果表明,提出的机会路由候选路由节点选择和排序算法能明显提高机会路由的传输性能。

Abstract: A transmission rate aware candidate forwarder selection and ordering algorithm based on expected transmission delay of nodes was proposed. It first separated opportunistic route forwarding into two components: the anycast forwarding from source node to its candidate forwarders set, and the remaining forwarding from that candidate forwarders set to destination, and then the shortest expected transmission delay of opportunistic routing was computed iteratively. Finally, candidate forwarders were selected and ordered according to the shortest expected transmission delay of nodes. The simulation results indicate that the proposed algorithm can improve the performance of opportunistic routing obviously.
