Hybrid Intelligent Monitoring Network Based on Ad hoc and Wireless Sensor Networks

摘要

For the applications of certain dangerous situations, such as battle field monitoring or dangerous explosives scenes etc, a wireless intelligent monitoring system based on ad hoc and WSNs (Wireless Sensor Networks) is proposed and designed accordingly. Mobile nodes in the ad hoc are constituted by smart cars with positioning, communication and monitoring functions, while the nodes in the WSNs are achieved by using Bluetooth technology and the embedded system technology. To improve the route quality of communication nodes in sparse environments, a model for mobile wireless network based on chain formation is proposed. Meanwhile, a standby node strategy and a smart ferrying information method based on Q-learning are also put forward to improve network survivability. For the Bluetooth wireless sensor networks in small size, a single path networking method based on kindred tree is proposed and implemented to simplify the network structure, leading to an increase of reliability. The simulation shows the network has the feature of small packet drop rate and better throughput, while the experiment shows that the complex network can finish monitoring tasks satisfactorily.
