无线传感器网络中基于服务质量管理的多目标优化控制
Multi-Objective Optimization Control Based on QoS Management in Wireless Sensor Network *
摘要
Abstract
In order to reduce the impact of inherent network time-varying delay, packet loss and other phenomena on performance of the remote monitoring and control system based on wireless sensor network, the multi-objective optimization control strategy based on network quality of service (QoS) management is proposed from the perspective of improving the overall system performance. For the real-time data transmission from the sensor nodes to the sink node, the proposed optimization control strategy uses the deadline miss ratio as the evaluating index of the QoS, and utilizes the PID controller to calculate the network bandwidth demands for all sensor nodes. Subject to the network bandwidth demands, the multi-objective optimization problem is formulated and solved, then the packet sending period of all sensor nodes is adjusted so that the network bandwidth allocation can adapt to the QoS changes, the QoS is maintained at a pre-determined desired level and other performance criteria is achieved. Preliminary experimentations indicate the rationality, effectiveness and practicability of the proposed optimization control strategy. It can be effectively applied to the greenhouse, the cropland, and the nursery garden, etc.关键词
