摘要
由于受到时钟准确性和精度要求的影响,传统网络中的时间同步算法已经不能满足无线传感器网络的要求。根据ZigBee郊术的特点,研究了基于CSMA-CA机制的具有针对性的信标同步算法。给出了相应的算法分析、算法流程,以及在NS2平台中的仿真结果与性能分析,同时给出了在信标网络与非信标网络中的效果对比。
Because the clock accuracy and precision requirements are often stricter in sensor networks than in traditional distributed systems, the algorithm of time synchronization in traditional networks can not be used in wireless sensor networks. This paper makes research on the algorithm of time synchronization based on CSMA- CA on the NS2 platform, simulates particularly on beacon-enabled network, and analyses the results to make some conclusions, including the comparison between beacon-enabled network and non-beacon network .
