Controlling sensor networks

摘要

A control element for a sensor network having a set of different sensors. In operation, the control element transfers connections between the control element and the set of different sensors, where the transfer connections are compliant with respective sensor-specific protocols. A sensor controller element is provided for each sensor, and establishes transfer connections between the control element and new sensors in runtime. Information obtained in a sensor-specific protocol format from the sensors is converted into a common format in the sensor controller elements. The common format information is processed by a set of common control components of the control element. The control element provides a service based on the information in the common format to at least one consumer, and updates the service in accordance with the sensors present in the sensor network.

1. A method for dynamically configuring a sensor network, the method comprising:
connecting a first sensor to a first control element in said sensor network; providing a sensor configuration information of said first sensor connected to said first control element to a second control element in said sensor network; disconnecting said first sensor from said first control element; connecting said first sensor to said second control element; generating a sensor controller corresponding to said first sensor, the generating said sensor controller including:
providing a sensor configuration repository that includes existing sensor controllers;evaluating compatibility of modules of existing sensor controllers; andcombining the compatible modules of said existing sensor controllers, the combined compatible modules becoming said generated sensor controller; requesting, by said second control element, the generated sensor controller associated with said first sensor; transferring said generated sensor controller to said second control element in response to said request; receiving, at said generated sensor controller of the said first sensor, messages from other sensors in said sensor network, the receiving the messages by said generated sensor controller asynchronized with receiving messages by other sensor controllers; and sending, by said generated sensor controller of said first sensor, requests to other sensors in said sensor network, the sending the requests by said generated sensor controller synchronized with sending requests by said other sensor controllers.
