Mobility extensions to industrial-strength wireless sensor networks

A system for sharing sensor data between a plurality of clusters of wireless devices in which at least one cluster of wireless devices of the plurality of clusters of wireless devices is mobile, the system comprising:

• a plurality of clusters of wireless devices comprising at least one cluster of wireless devices that is mobile and at least one cluster of wireless devices that stores sensor data;
• a first cluster of wireless devices of the plurality of clusters of wireless devices configured to transmit a beacon comprising information identifying the first cluster of wireless devices,
• a second cluster of wireless devices of the plurality of clusters of the wireless devices configured to receive the beacon of the first cluster of wireless devices;
• wherein the second cluster is configured, responsive to and using the beacon, to establish a time synchronized two way wireless communication with the first cluster;
• and
• wherein one of the first cluster or the second cluster is configured to receive, via the time synchronized two way wireless communication, sensor data stored at the at least one cluster of wireless devices.
