摘要
针对无线传感器/执行器网络中的传感器-执行器和执行器-执行器协同工作问题,分别提出了一种分布式的解决方案。根据传感器与执行器的部署情况,传感器-执行器协同工作可归结为一个多源信息估计及融合问题。基于这个特点,设计了一种能在传感器和执行器上并行运行的联邦滤波器。同时考虑到时间、能量、控制指标等要求,提出了一种基于事件驱动机制的执行器任务分配机制来协同执行器之间的工作。仿真表明所提算法能够满足控制系统的性能要求。
In order to coordinate sensors and actuators in wireless sensor and actuator networks (WSANs) in an effective manner, corresponding distributed solutions are proposed. According to the nodes deployment, sensor-actuator (S-A) coordination can be formulated as a multi-source information fusion problem. So, a federated filtering run parallel in sensors and actuators is designed to coordinate S-A. Then, taking time, energy and control requirements into consideration, an actuator-actuator (A-A) coordination mechanism is introduced that enables coordinating action of the participating actuators based on the event-driven task allocation mechanism. Simulations demonstrate the effectiveness of proposed methods.
