摘要
传感器网络中的节点定位和能量消耗问题一直是被研究的重点问题,由于机器人技术的快速发展,利用移动机器人精确定位成为可能。采用移动机器人广播多能量级信号,可以实现对未知节点位置精确估计,同时还可以搜集未知节点的数据信息,使未知节点不会因为在网络中传输采集到的数据而消耗太多的能量。仿真实验结果表明,该精确定位算法能较好地达到预期的效果,并在节省节点能量上有深远的影响。
The sensor network node location and energy consumption have been a very important question. Because of the rapid development of robot technology,it is possible to use a mobile robot for fine - grained localization. Mobile robot broadcasted multi - energy - level signals. Accurate location of the unknown nodes could be achieved, and data of unknown node can be collected. So unknown nodes do not consume too much energy, because of sending data in wireless sensor networks. The simulation results show that, it can be satisfied with this precise position algorithm, and it is further far - impact on saving node energy.
