| 摘 要： | 为了能够在延迟容忍网络中缓解拥塞部分的流量,使网络保持高缓存可用率和低延迟,提出了一种拥塞感知转发算法。在社会路由度量和自我网络度量的基础上,该算法采用了一种新的具有更高可靠性和灵活性的整合度量。运用实验将该算法与Epidemic,Prophet和Spay and Focus这3种经典路由算法就交付率、延迟和缓存可用率3方面进行了比较。实验结果表明,这种算法具有优异的性能。

| Abstract: | To alleviate the flow from congested parts in delay tolerant network and maintain high buffer availability and low delays for the network,a kind of congestion perception forwarding algorithm is put forward.Based on the social routing metric and ego network metric,a new integrated metric of higher reliability and flexibility is adopted by the algorithm.Experiments are conducted to compare the algorithm with epidemic,prophet,spay and focus protocols over success ratio,delay and availability of buffer.The results show that this algorithm had excellent properties. |
