RFID系统中面向服务的动态资源配置优化机制

Service-oriented dynamic resource configuration optimization scheme in RFID system

针对物联网中RFID(radio frequency identification)系统的tag和reader的速率不匹配及其资源受限问题,从理论上对tag和reader之间的协作通信上下文进行分析,提出一种面向服务的RFID系统资源配置优化机制,该机制利用tag与reader的组件QoS(quality of service)信息建立闭环控制框架,使用3种控制策略根据其资源状态和类型调节QoS参数。通过实验对机制进行了性能分析和验证,结果表明,该优化机制有效地提高RFID系统的吞吐量,高效地使用系统资源,减少了能量消耗和reader-to-reader干扰。

Aiming at the defect that the rate between tag and reader was not match and their resource-constrained problem in the radio frequency identification （RFID） systems, the collaboration communication context was analyzed theoretically Service-oriented dynamic resource configuration optimization scheme of RFID system was proposed which used the component quality of service（QoS） information of tag and reader to establish closed-loop control framework and devel- oped three control strategies to adjust QoS parameter according to the state and type of its resources.The scheme was analyzed and validated for performance through experiments.The numerical experiments results show that the optimiza- tion mechanism make throughput of RFID systems improve, use resources efficiently and reduce the energy consumption and interference of reader-to-reader.
