20110241846 | Technique For Effective Communications With Mobile Sensors In A Sensor System - In a sensor system, an edge element receives data from at least one mobile sensor, and sends the data which may be preprocessed by the edge element to a server for further processing. The edge element may communicate to the mobile sensor to change a value of a run-time parameter in the mobile sensor to affect its operation. The edge element may also cause the mobile sensor to upgrade its firmware. When the mobile sensor is about to leave communication coverage of the edge element, the latter may initiate a peer-to-peer handover of the control and administration of the mobile sensor to another edge element in the sensor system. | 2011-10-06 |
