IoT(Internet of Things)systems are facing more and more challenges ,such as increasing network size ,diversities of sensors ,complexities of protocols and difficulties of management with expansions of its applications .So ,we proposed a novel technique of plus and play which provides functions of service discovery ,intelligent configuration and service mapping .Beside ,we designed a fuzzy adaptive configuration method ,named as EasiFLC .Experimental results show that when application′s require-ments ,topologies of sensing layers or wireless channel conditions change ,EasiFLC adjusts network parameters dynamically ,thus it ensures quality of services with lowest cost ,and achieves good environmental adaptability ,strong robustness .%随着应用领域的不断拓展，物联网面临着网络规模巨大、感知节点多样、通信协议繁杂及资源管理困难等挑战。针对上述挑战，本文提出了物联网即加即用（plus and play ）技术，可以完成物联网服务发现、智能配置、服务映射等功能；具有支持异构网络通信、动态网络扩展、协同信息处理等特点。在此基础上，为实现即加即用的关键功能智能配置，本文提出了一种模糊自适应配置方法EasiFLC （Easinet Fuzzy Logic Control ）。通过真实场景的实验表明，EasiFLC在应用层需求、无线通信环境、感知层拓扑结构变化时，通过动态调整网络参数以最小代价保证服务质量，并具有较好的网络环境适应性和鲁棒性。
