摘要
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。
The random mobility of nodes and the exhaustion of energy make the Ad Hoc network form partially- connected state. In order to guarantee effective data transmission in these special networks, an on-demand routing technology based on task relay is proposed. The communication between connectionless areas is realized by using task relay nodes, and the simulation by NS2 simulation software indicates the availability of this technology.Influence of moving speed and communication distance of the task relay nodes on delay is also analyzed.
