摘要 无线传感器网络室内定位系统中的参考节点长期处于工作状态会浪费整个传感器网络的能量,缩短系统的生命周期.采用合理的网格化布局和参考节点周期休眠机制,可以保证系统正常工作,使得绝大部分参考节点周期性进入休眠状态.这种方法节省了整个网络的节点能量;同时也有效地减少了相邻节点间信号冲突问题;又使得接收到的3个参考节点位置信息呈线性关系的概率降低,提高了系统的工作效率. Beacons are in working state along for indoor location can waste energy, and shorten the life time in wireless sensor network. It makes system run healthy and the most of beacons change into sleep by taking reasonable grid layout and cycle sleep mechanism, which saves the whole beacon＇s energy, reduces signal collisions between beacon neighbors, lowers the probability of three beacon nodes coordinates in linear, and enhances system efficiency.
