  • Data collection protocol for wireless sensor networks
    Patent number: 8022822
    Abstract: 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).
    Type: Grant
    Filed: June 27, 2008
    Date of Patent: September 20, 2011
    Assignee: Microsoft Corporation
