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 requirements

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.
