面向煤矿井下WSN低功耗双向时间同步算法研究与实现
Research and Implementation of Low Power Two-Way WSN Time Synchronization Algorithm for Coal Mine
摘要
Abstract
The energy consumption problem that exists in traditional time synchronization algorithm because of ex-changing more packets to obtain synchronization accuracy. According to the special network structure in underground coal mine, on the basis of the analysis of bidirectional pair and one-way broadcast synchronization mechanism,combine both synchronization mechanisms with the transmission characteristics of radio effectively,and a two-way synchronization algorithm based on clusters structure which at the characteristics of the passive and low power is proposed. Experiments show that,synchronization algorithm which been proposed can solve the problems of exchanging packets frequently effectively,in the range of allowable error can reduce message consumption and bal-ance the network energy.关键词
