Information-based self-organization of sensor nodes of a sensor network
| DWPI Title: Operating method of sensor nodes used for e.g. securing borders, facilities and community events involves sending at least one communication to other sensor node being the information neighbor in response to information-based event |
| Abstract: A sensor node detects a plurality of information-based events. The sensor node determines whether at least one other sensor node is an information neighbor of the sensor node based on at least a portion of the plurality of information-based events. The information neighbor has an overlapping field of view with the sensor node. The sensor node sends at least one communication to the at least one other sensor node that is an information neighbor of the sensor node in response to at least one information-based event of the plurality of information-based events. |
| Use: For operating sensor nodes used for e.g. securing borders, facilities and community events, and for home security systems. |
| Advantage: Maintains robustness of the decision-based fusion for event detection and data-based fusion for event extraction and tracking across the sensor field. Maintains connectivity and maximizes bandwidth through the wireless channel between sensor nodes based on the cost and power consumption. Ensure that no power is wasted by the sending and receiving sensor nodes. |
| Novelty: The method involves detecting information-based events and determining whether at least one sensor node (30) is an information neighbor based on a portion of information-based events. The information neighbor has an overlapping field of view with the sensor node. The sensor node is adapted to send at least one communication to the other sensor node being the information neighbor in response to the information-based event. |
