| 摘 要： | 对DTN网络中PRoPHET路由协议进行了改进,在采用基于效用值来选择DTN路由下一跳的同时,充分利用了临时簇内的端到端的连接.另外,当网络中发生了DTN拥塞时,把拥塞节点上紧急程度低的信息转移到临时簇的周围其它节点,然后传输紧急程度高的信息到拥塞节点.仿真结果表明,与DTN网络中路由协议PRoPHET相比,改进后的路由方法提高了数据包的成功发送率,降低了平均发送延时.

| Abstract: | An improvement in PRoPHET protocol is proposed in the paper in which an end-to-end connecton in the temporary cluster and the rouing adaptation which the less emergent messages in the congestion node are transferred to some other node in the temporary cluster then the more emergent messages to the congestion node when the DTN congestion occurs in the network is utilized besides the basic utility method. The performance is analyzed and compared to the PRoPHET protocol in the paper.As the simulation results s... |
