Internet of Things (IoT) devices and methods of operating the same are disclosed. A method may include registering a set of services configured for execution on a producer IoT device with a producer management application, and broadcasting or multicasting a system service advertisement as a first system signal via a given system signal protocol to notify one or more consumer IoT devices that one or more services of the registered set of services are available via the producer IoT device. The producer IoT device receives, in response to the system service advertisement, at least one request for a service announcement from at least one of the consumer IoT devices, and the producer IoT device unicasts, in response to the request, the at least one service announcement that announces the set of services to the at least one consumer IoT device as a second system signal via the given system signal protocol.
