Abstract: A face recognition method for an edge device is provided. Firstly, a recognition data is received from a computing device through a wireless network. Then, a trained model is retrieved from the recognition data. Then, the trained model is stored. Then, a face detection operation is performed to acquire a face image and a face temperature of a detected face. When the face temperature is within a human body temperature range and the face image complies with the trained model, the edge device confirms that the detected face is a face of a real person and the real person is a known user.

Abstract: An access point (AP) accepts a communications device to join a wireless communications network. The AP registers a service provided by the communications device. The service is available in accordance with a schedule and a set of service parameters. The AP receives a request from a peer communications device seeking the service. The AP announces availability of the service on behalf of the communications device while the communications device is unavailable. The service is later provided by the communications device to the peer communications device when both devices are available to communicate. By utilizing an always-on AP to announce service availability and to exchange service parameters, fast service discovery can be achieved with low power consumption for both service advertisers and service seekers.

Abstract: A device-centric discovery mechanism requiring very low power consumption to find out information about each other directly in a self-managed mobile environment is proposed. A mobile communications device joins a self-managed communications network, which does not have a centralized management entity. The mobile device receives a request from a peer communications device about publishing a service or subscribing to a service in accordance with a first schedule. The mobile device announce the request on behalf of the peer communications device in accordance with a second schedule. The service is then provided by a service advertiser to a service seeker in accordance with a third schedule.

Abstract: A linking method employed by a first communication device includes: transmitting a first network domain information to a second communication device before/after a link with the second communication device is established; receiving a second network domain information from the second communication device before/after the link with the second communication device is established; and when the first communication device is decided to be a group owner before/after the link with the second communication device is established, determining a network domain address of the link according to the first network domain information and the second network domain information.
