摘要
在间断连接无线互联网络中,由于自然干扰或人为因素影响,节点之间无线链路通常在时间上具有间断特性,这就为间断连接无线互联网络的选路问题提出了新的挑战。文章在链路统计特性的基础上,重点分析了运用动态规划方法求解该问题的基本思路。并且给出了该方法的基本方程,从理论上分析了该方法的正确性和有效性。
In the discontinuously connected wireless network, because of nature disturbing or man-made influence, the wireless links between the nodes usually are of interruption characteristics in the time. So, it is a new challenge to the routing in the discontinuously connected wireless networks. This paper, based on the statistic characteristics of the link, analyzes the main idea in resolving the routing in this kind of network by dynamic programming. In addition, basic equation of the dynamic programming is provided, and theoretical analysis proves the correctness and validity of the method.
