摘要
理论分析指出,一些不基于测距的WSN定位算法往往需要节点间进行大量的信息交互,存在大量的突发性通信,降低了网络工作效率,浪费了WSN中宝贵的能量。针对此问题,在定位算法中引入数据融合技术,通过仿真验证,引入数据融合的定位算法可以有效的减少执行定位算法所需的无线分组个数和总的通信量。
Theoretical analysis shows that some rangefree WSN localization algorithms need a lot of information exchanges, which results in lots of abrupt communications. It may affect the efficiency and waste the energy, which is very sensitive to WSN. In order to cope with this problem, a new localization algorithm is proposed, which is based on the data fusion technology. The simulation results shows, the proposed algorithm could reduce the number of the packets and the total traffic of communications effectively.
