带有相遇预测的自适应路由机制

机会网络中的喷洒等待(spray and wait,SnW)路由机制在消息转发决策时并未考虑相遇节点的转发能力。针对SnW在选择中继节点时的盲目性,提出了一种带有相遇预测的自适应路由机制,通过动态地感知网络中节点的信息,根据节点转发能力的差异,自适应地选择活跃度高、与目标节点相遇概率高的节点作为中继节点。结果表明,在不增加开销的情况下,提出的路由投递延时更低,投递率更高。

Adaptive routing mechanism with encounter prediction

The forwarding ability of encountering node has not been taken into account in opportunistic networks by spray and wait(SnW) mechanism. To overcome the blindness on relay node selecting, an adaptive routing protocol with encounter prediction is proposed in this paper. The nodes status in the networks will be obtained dynamically, and the messages are forwarded to nodes which have higher activity and meeting probabilistic with destination. Simulation result shows that our proposed mechanism achieves lower latency and higher delivery probabilistic.
