摘要
针对传感器网络对目标的跟踪问题,提出一种传感器优化调度方法。该方法以传感器使用成本和允许激活的最大传感器数量为约束条件,把最小化目标位置误差作为优化目标,运用二进制凸规划技术对优化调度问题进行建模,采取逼近算法迭代求解规划模型。蒙特卡罗实验表明,对于节点数目小于70的传感器网络,优化调度方案可以获得高精度的目标跟踪结果。
An optimal sensor scheduling method is proposed for tracking target that moves through the sensor networks. The method aims at minimizing the predicted approximate error in the target position estimate subject to the con- straints on sensors usage costs and maximum allowed sensor number. The scheduling problem is modeled using binary convex programming, which is then solved by outer approximation algorithms. Monte Carlo simulation results shows that the scheduling scheme can tracking the target with high precision.
