一种基于DTN的震后救援路由新策略
发布时间：2018-07-31 10:22
【摘要】：地震灾害发生以后,原有电力系统和通讯设施不能够正常运行,使得搜救人员携带的无线通讯节点设备组成的DTN(Delay Tolerance Network)成为了搜救服务网络的重要组成部分。搜救信息是否能够第一时间传送到数据中心尤为重要,分析了震后救援特性需求,设计了地震救援系统模型,综合考虑搜救网络节点间的时间距和数据信息的权重优先级提出了一种适宜于震后救援的路由新策略,通过实验仿真验证了新策略的实用性,为我国地震震后救援提供参考。
[Abstract]:After the earthquake disaster, the original power system and communication facilities can not operate normally, which makes the DTN (Delay Tolerance Network) composed of wireless communication node equipment carried by search-and-rescue personnel become an important part of the search and rescue service network. It is very important whether the search and rescue information can be transmitted to the data center in the first time. This paper analyzes the characteristic demand of the post-earthquake rescue, and designs the model of the earthquake rescue system. Considering the time distance between search and rescue network nodes and the weight priority of data information, a new route strategy suitable for post-earthquake rescue is proposed. The practicability of the new strategy is verified by experimental simulation, which provides a reference for post-earthquake rescue in China.
