Abstract
In the network-based group management and floor control mechanism disclosed herein, a server may receive a request to occupy a shared IoT resource from a member device in an IoT device group and transmit a message granting the member IoT device permission to occupy the shared IoT resource based on one or more policies. For example, the granted permission may comprise a floor that blocks other IoT devices from accessing the shared IoT resource while the member IoT device holds the floor. Furthermore, the server may revoke the permission if the member IoT device fails to transmit a keep-alive message before a timeout period expires, a high-priority IoT device pre-empts the floor, and/or based on the policies. Alternatively, the server may make the shared IoT resource available if the member IoT device sends a message that voluntarily releases the floor.
