摘要： Systems and methods that provide for collection of sensor data in a wireless network with a dynamically changing structure. A data collection protocol exploits the self-awareness capabilities of nodes in selection of tree structures that form the wireless network during communication with a base station. The data collection protocol can further include a topology control component (which regulates how nodes are distributed among various tree structures and associated communication channels with the base station) and data retrieval component (which coordinates among the sensors to transmit data packets containing sensor data to efficiently employ available bandwidth).

摘要： A commercial frequency-modulated (FM) radio signal indoor localization system and method for finding a location of a mobile embedded device (such as a smartphone) within a building. Indoor localization is performed by receiving commercial FM radio signals on the device, analyzing the signals using signal quality metrics, and generating signal quality vectors for each signal and signal quality metric used for the signal. The signal quality metric can be any physical signal quality indicator. The signal quality vectors are added to obtain a current location fingerprint. The current location fingerprint is compared to fingerprints stored in a fingerprint database. The location associated with the stored fingerprint that is the closest match to the current fingerprint location is designated as the current location in the building of the mobile embedded device. Locally generated radio signals can be used in conjunction with the commercial FM radio signals to improve localization accuracy.

摘要： A “Communication Device with Energy Efficient Sensing” provides various techniques for enabling a variety of sensor-based applications and processes while conserving energy on mobile communications devices. More specifically, the Communication Device with Energy Efficient Sensing provides a novel sensing architecture for mobile communications devices where sampling and, in various embodiments, processing, of sensor data received from one or more sensors is offloaded to a dedicated low-power processor having the capability to interact with a primary processor of the communications device. Such sensors include, but are not limited to accelerometers, ambient light sensors, compasses, microphones, pressure sensors, touch sensors, low-power radio devices, etc. This approach enables the communications device to perform continuous sensing with a low power overhead. In various tested embodiments, it has been observed that that the sensing architecture described herein can be two to three orders of magnitude more energy efficient in comparison to conventional communications devices.

摘要： The subject disclosure is directed towards mobile network management by reducing energy consumption and increasing a lifetime of one or more nodes. By determining a beacon listening duration and a beacon listening period in response to an energy budget, each node may minimize or reduce latencies associated with node discovery and/or node group maintenance. The beacon listening duration and the beacon listening period is used to compute a beacon broadcasting duration and a beacon broadcasting period such that advertising beacon transmissions and advertising beacon receptions occur at substantially concurrent time slots between low power states. These advertising beacons are used to propagate and maintain group membership information amongst the one or more nodes.
