Cooperative Time Synchronization Based on Mining Wireless Sensor Network

Abstract:

With the energy market demand increasing, coal mine safety production monitoring system based on wireless sensor network has been widely used. The traditional wireless sensor network synchronization method based on packet switching is very difficult to achieve synchronization accuracy and energy consumption at the same time. Paper presents a cooperative time synchronization method based on packet message exchange (CTS), Analysis of synchronous packet information interaction process, the introduction of cooperative relay will not change the synchronization precision. Synchronous grouping information for sending and receiving ends for receiving and forwarding to reduce the transmission power, reduce energy consumption through cooperative relay. Theoretical analysis and computer simulation show that in the condition of not reducing the synchronization precision, it can achieve the purpose of reducing energy consumption by introducing the cooperative relay in the horizon channel model can reach 4 times the energy efficiency.
