摘要 该文提出了一种基于动态分簇的协同信息处理算法,并以跟踪问题为具体算例对该算法进行了验证。该方法依据被跟踪对象的预测位置,动态分簇(cluster),并利用传感器节点与该预测位置间的范数来选择合理的测量值,综合利用簇内所有相关节点的信息。仿真结果表明,该方法在有效利用能量的基础上大大提高了系统精度和鲁棒性。 This paper presents a dynamic clusters organized algorithm for tracking the moving objects in wireless sensor networks.This algorithm is based on the collaborative signal and information processing(CSIP)technology which is devel-oped by Zhao.Simulation results show that the dynamic clusters organized algorithm significantly improves the system performance because of utilizing more information.
