Abstract
A device and service discovery method and a piece of device middleware are provided. The method includes that a user terminal device broadcasts its own device information and service capability information, and searches for information about a surrounding service network, information about a device not joining the service network and service capability information about the device; if it is discovered that a service network, which has a service capability needed by the user terminal device to accomplish a service, exists in the surrounding area, the user terminal device is configured to join the service network, and interact with a central node of the service network to accomplish the service; and if the service network is not discovered, the user terminal device selects a central node from devices which do not join a service network and have a service capability needed by the user terminal device to accomplish the service, is configured to generate a service network according to the selected central node, and interact with the selected central node to accomplish the service. A ubiquitous service can be provided through discovery, acquisition and networking of surrounding available…
