    Abstract: An embodiment of the invention relates to a local area sensor network including a central unit configured to receive a resource allocation request from a priority network sensor in a reserved timeslot and in response to designate a shared timeslot allocation. The priority network sensor transmits a resource allocation request in a reserved timeslot, and the sensor transmits data in the allocated shared timeslot. A sensor network can be formed with multiple gateways that each communicate over wired and wireless portions of the network. The central unit communicates with the gateways over the wired portion of the network. Wireless nodes communicate wirelessly with the gateways. The central unit receives a plurality of link quality indicators from the gateways for respective wireless paths to the wireless sensors, and selects a gateway for relaying a message from the central unit to a wireless sensor based on the link quality indicators.

    Abstract: An apparatus for generating trusted image data includes an image data generator, a processor and an output unit. The image data generator generates image data of an image to be taken of a three-dimensional scene and trust data of the three-dimensional scene. The trust data indicates a depth information of at least one pixel of the image to be taken or comprises data capable of being used to calculate a depth information of at least one pixel of the image to be taken. The processor generates encrypted image data by encrypting at least the trust data or characteristic data derivable from at least the trust data, so that an authentication of the image data is enabled based on the encrypted image data. The output unit provides trusted image data including the encrypted image data.
