  abstract = {When disaster strikes, the rapid deployment of Wireless Sensor Networks (WSNs) in the disaster area is helpful for real-time monitoring of environmental indicators and improving the efficiency and quality of emergency rescue. In the meanwhile, seveal factors such as the unpredictability of disaster, harsh environment and the urgency of network system put forward lots of special needs in network architecture, sensor nodes designing, and technical realization. This paper proposes a new routing framework for building WSNs in emergency circumstances. In particular, a mobile access mechanism based on the X-MAC protocol has been designed. An effective path of interest propagation strategy, where the WSN node positions have been used to guide the interest spread, has been proposed. Experimental results demonstrate that our proposed framework can significantly reduce the network traffic and energy consumption in directed diffusion.},
