Abstract
An access authorization method and apparatus for a wireless sensor network comprises at least a base station and a wireless sensor network formed by a plurality of sensor nodes. After having obtained an access authorization of a user, the at least a base station issues a request message to a target sensor node in the wireless sensor network. The target sensor node requests at least a controlling node in the wireless sensor network for sensing data sensed by the at least a controlling node, and checks if the sensing data meets the requirements of the access authorization of the user. Whether the target sensor node responds with the required multimedia or not is based on the checking result.
