Providing handover capability to distributed sensor applications across wireless networks

Abstract

Improved capabilities are described for increasing the bandwidth in a wireless communication network, such as where host computers provide publish-subscribe broker services to a sensor device and a communicating entity. A queuing service application may provide service packet continuity when the sensor device or the communicating entity moves between two wireless RF access nodes (in the same or different wireless networks). The publish-subscribe broker network is adapted to route packets of sensor data, on behalf of the sensor device that publishes the sensor data, to a sensor-processing application, wherein the sensor-processing application subscribes to the sensor data, and wherein the sensor-processing application generates application data that is at least in part sensor data from the sensor device. The publish-subscribe broker network is adapted to route packets of the application data, on behalf of the sensor-processing application that publishes the application data, to the communicating entity if the communicating entity subscribes to the application data. The queuing service application connects to the publish/subscribe broker network and subscribes to receive packets of the application data matching the packets being sent to the communicating entity, wherein the queuing service application makes available the matching application data packets to replace application data packets that the communicating entity did not receive during a time when the sensor device or the communicating entity transitions between connections with the two wireless RF access nodes.
