自组织网络中节点随机移动,能源耗尽等因素易使网络形成部分连接状态。为保证该特殊网络中的数据有效传输,文中提出了一种基于任务接替的按需路由技术,利用数据传输任务接替节点实现部分连接网络中无连接区域间的相互通信,并采用NS2网络仿真器验证了该路由技术的有效性以及分析了任务接替节点移动速度、网络节点通信距离对通信时延的影响。
Self-organizing network nodes move randomly, depletion of energy and other factors make the network easy to form part of the connection state. In order to ensure the effective transmission of the data in this special network, an on-demand routing technology based on task takeover is proposed in this paper. The data transfer task is used to replace the nodes to realize the mutual communication among the connectionless areas in the partially connected networks. The NS2 network emulator The validity of this routing technology is verified and the effect of task takeover node moving speed and network node communication distance on communication delay is analyzed.
