基于DTN的地震应急通信路由协议的研究
Research on DTN-based Routing Protocol of Earthquake Emergency Communication
摘要
Abstract
Sichuan is one of Chinese earthquake-prone provinces,which has the complex topography including lots of mountains,hills and highlands.After the earthquake,the electric power,communications facilities and traffic environment of earthquake-stricken areas have suffered great damage where the earthquake emergency communication exhibit the characters alike DTN.And it's important for commanding and relief work after the disaster to choose the appropriate kind of routing protocol,aiming at the special landform of Sichuan Province,to guarantee the quality of earthquake emergency communication.The communication needs of earthquake emergency communication system are classified and different communication environment models of earthquake emergency communication,applying to Ya'an as an example,are built.Then the routing protocols which is optimum for Sichuan Province's special terrain are simulated and selected by the tools such as ONE.Besides,the DTN's routing protocols' influence is analyzed on the communication qualifies in different circumstances based on the different communication environment models,making contributions to the references of relief deployment strategies.关键词
