中文摘要：

施工隧道是一种狭长封闭、环境恶劣、且事故多发的空间,对监控网络的可靠性和实时性要求高。根据正常监测和紧急状况下对网络路由协议的不同要求,监控网络存在两种数据传输模式：一是常规通信模式,二是紧急通信模式。针对隧道中无线传感网络的部署特点,提出一种基于定向扩散原理的紧急路由协议,以保证紧急通信模式下路由协议的实时性和可靠性。实验表明,该路由协议能满足施工隧道监控网络在紧急模式下的实时通信需求。

英文摘要：

Tunnel construction is an infrastructure with chain-type space,severe environment,and high accident potential,which intensively demands a reliable and real-time monitoring network.Considering the different requirements between normal monitoring and emergency situation in the tunnel construction,there should be two data transmission modes：normal data transmission mode and emergency data transmission mode.To cope with the characteristic of the deployment to wireless sensor network in tunnel,an emergency routing protocol based on Directed Diffusion,DD-ERP,had been proposed in this paper to ensure a routing with real-time constraint and perfect reliability under emergency data transmission mode.The experiment indicated the DD-ERP protocol could satisfy the real-time data transmission in emergency situation of the tunnel construction.
