摘 要：Monitoring system design of mine gas Monitoring System were designed according to the traditional lacked of the real-time and early warning functions and so on problems.A multi-hop sensor network based on TinyOS is designed.The system is based on hierarchical network architecture.The software design principle based on TinyOS is introduced,which can realize the multi-hop communication.A simple Ant colony algorithm is designed in this sensor network to improve the network lifetime.According to simulation results and Test Research,this system can efficiently realize the multi-hop data communication and reliable.
