针对无线传感器/执行器网络(Wireless Sensor and Actuator Networks,WSANs)中执行器控制域的数据收集问题,提出了一种基于执行器控制域的分布式数据收集协议(DG-ACD协议).DG-ACD协议从能量有效性和数据融合的角度,提出了执行器控制域内传感器节点的中继代价函数,并以执行器节点为中心,采用发射功率分级递进的路由建立方式,为控制域内的每个传感器节点寻找其到达执行器节点的中继节点,从而实现对执行器控制域内传感器节点的聚集和数据收集.实验仿真结果表明,网络中节点(包括执行器节点)部署完成后,DG-ACD协议能有效地将网络中的传感器节点聚集到相应的执行器节点,并在数据收集的能量有效性、实时性和稳定性上均有良好表现.
In order to solve the problem of data collection in the actuator control domain of Wireless Sensor and Actuator Networks (WSANs), a Distributed Data Collection Protocol (DG-ACD) based on actuator control domain is proposed.DG- ACD protocol from the energy efficiency and data fusion point of view, the actuator control domain sensor nodes in the relay cost function, and the actuator node as the center, the use of transmit power hierarchical progressive routing establishment for the control domain Sensor nodes to find the relay nodes which reach the actuator nodes so as to realize the aggregation and data collection of sensor nodes in the actuator control domain.The experimental simulation results show that after the deployment of nodes (including actuator nodes) in the network is completed, the DG-ACD The protocol can effectively gather the sensor nodes in the network to the corresponding actuator nodes and perform well on the energy efficiency, real-time and stability of data collection.
