摘要
针对ZigBee网络节点在大规模的数据通信过程中,会因为通信时域不一致引起冲突的问题,提出了一种基于三角校验碰撞预测的放信道信号冲突机制。运用对同一节点进行通信的信号组成一个多信号虚拟校验区域。通过建立的无线传感信号碰撞冲突检测模型进行通信时域冲突的预测判断。通过时域内的信号二维区域碰撞预测,计算碰撞的可能概率。实验结果表明,运用该方法能够对大数据、对节点、长时间的ZigBee通信网络通信进行优化,提高了节点信道的通信效率。同时,这种方法还大幅降低了无线通信网络的数据碰撞的可能性。
ZigBee network nodes in the great scale of data communication, communication does not agree for time domain by the conflict is put forward based on triangle calibration collision prediction of the channel conflict put signal mechanism. The same node of communication of the signal more than a signal virtual calibration area is used. Through the establishment of the wireless sensor signal collision detection model conflict time domain is pre diction of communication conflict judgment. Through the time domain signals of 2 d regional collision forecast, the collision of the may probability is calculatied. The experimental results show that the method can be used to big da ta, to node, long ZigBee communication network communication optimization. The efficiency of the node channel communications is improved. At the same time, this method greatly reduces the wireless communication network da ta of the collision of the possibilities.
