在无线监测网络中,无线嗅探器被布置在网络区域内监测用户的活动。这可用于故障诊断、资源管理和关键路径分析。由于硬件的限制,无线嗅探器通常在一个时刻只能收集一个信道上的信息,因此,优化嗅探器的信道选择以最大化收集的信息,进而最大化网络监测质量(QoM)就成为一个关键问题。在本文中,作者提出一种基于粒子群优化的方法以达到优化的信道选择。设计了一种二维映射粒子编码及其移动策略;引入蒙特卡罗方法来修正进化过程中的解,显著提高了算法的收敛性。大量仿真结果表明这种蒙特卡罗增强的粒子群优化算法(MC-PSO)明显超出了相关算法的性能,并具有更高的监测质量、更低的计算复杂度、更快的收敛性。实际测试也证明了算法的有效性。
