Spatio-cohesive service discovery and handover methods for distributed IoT environments are disclosed. The spatio-cohesive service discovery and handover methods include discovering a set of IoT (internet of thing) resources for providing a set of services which is a set of functionalities necessary for a task in distributed IoT environments, wherein the discovering a set of IoT resources may discover the set of IoT resources through a spatio-cohesive method considering spatial distance between a user and a service and between two services.
