一种新的移动自组网的数据传输策略*

为了提供移动自组网端到端的健壮的数据传输策略，对基于地理信息的路由协议进行优化，重点解决由于骨干节点停止工作后容易导致的整个网络快速崩溃问题，实现了能量的均衡。同时，根据排队理论，提出了一种移动节点的数据传输等候队列的调度策略，增加了移动自组网的端到端可靠的数据传输。基于NS的仿真实验，从路由协议选择、路由协议优化、数据传输等候队列调度策略方面展示提出的传输策略的优势。实验结果表明，该传输策略提高了节点能量利用率和节点生存时间，增加了数据传输的成功率，提高了网络的稳定性。

New data transmission scheme in mobile Ad hoc networks

In order to provide the robust end-to-end data transmission scheme in mobile Ad hoc networks, this paper proposed the geographic routing protocol optimization, solved the problem of the rapid collapse of the whole network due to the super node invalidity, and realized the energy equalizing. Moreover, according to the queue theory, put forword a scheduling schemefor the data transmission waiting queue of mobile nodes for theefficient end-to-end data transmission in mobile Ad hoc networks. Then showed the transmission scheme superiorityfrom routing protocol selection, routing protocol optimization and data transmission scheduling scheme through NS simulation experiments. While simulation results show thatthe transmission scheme can improve the surviving time and energy efficiency of mobile nodes, and increasethe success rate of data transmission, improve the network stability efficiently.
