Abstract:

Systems and methods for managing nodes in mesh networks are provided. A parent node may switch PANs and coordinate the switch with its child nodes. The parent node and its child nodes may maintain timing synchronization information for a current PAN and a new PAN. The parent node and its child nodes may switch to the new PAN using the same switching time.

Abstract:

Systems and methods are disclosed for distributed data transmission in an RF mesh network or other data network. An exemplary system includes at least two distribution devices. A first distribution device can receive a first data message that includes a first header and payload data. The first distribution device can determine that the second distribution device is not identified in the first header as receiving the payload data. The first distribution device can generate a second data message based on determining that the second distribution device is not identified in the first header. The second data message includes the payload data and the second header. The second header identifies the second distribution device as being selected to receive the payload data. The first distribution device transmits the second data message to the second distribution device.
