【摘要】:地震災(zāi)害發(fā)生以后,原有電力系統(tǒng)和通訊設(shè)施不能夠正常運(yùn)行,使得搜救人員攜帶的無(wú)線通訊節(jié)點(diǎn)設(shè)備組成的DTN(Delay Tolerance Network)成為了搜救服務(wù)網(wǎng)絡(luò)的重要組成部分。搜救信息是否能夠第一時(shí)間傳送到數(shù)據(jù)中心尤為重要,分析了震后救援特性需求,設(shè)計(jì)了地震救援系統(tǒng)模型,綜合考慮搜救網(wǎng)絡(luò)節(jié)點(diǎn)間的時(shí)間距和數(shù)據(jù)信息的權(quán)重優(yōu)先級(jí)提出了一種適宜于震后救援的路由新策略,通過(guò)實(shí)驗(yàn)仿真驗(yàn)證了新策略的實(shí)用性,為我國(guó)地震震后救援提供參考。
[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.
