Intelligent multi-bean medium access control in ku-band for mission-oriented mobile mesh networks
First Claim
1. A method for control of a wireless mesh network comprising:
- implementing a multi-layered media access control protocol for coordinated transmission among a plurality of nodes of the wireless mesh network, wherein the wireless mesh network comprises a moving airborne network operating in a Ku-band frequency range, at least one of the plurality of nodes comprises a mesh router (MR) and at least one other of the plurality of nodes comprises a mesh client (MC), and wherein at least the MR node comprises a multi-beam smart antenna (MBSA);
adapting parameters in the layers of the media access control protocol to schedule a Ku-band frequency data transmission among the plurality of nodes of the wireless mesh network, wherein all of the beams of the multi-beam smart antenna are concurrently either transmitting or receiving during the Ku-band frequency data transmission; and
predicting state transitions between the plurality of nodes of the wireless mesh network using a mathematical model, wherein said state transitions comprise a next interval Ku-band frequency communication between the MR and the MC and the prediction includes which beam of the MBSA will be used to communicate with the MC in the Ku-band frequency range, a traffic type of the next interval Ku-band frequency communication, and required airtime for the next interval Ku-band frequency communication and the prediction is based at least in part on mobility of the MR and/or the MC.

Abstract
A MAC design for Ku-band mobile wireless mesh network with multi-beam smart antennas is disclosed. This MAC includes an overlay control that separates the collision domain. It also has lower layer CSMA-like scheme. The disclosed design includes an enhanced PCF and an enhanced DCF for two purposes: (1) exploiting multi-beam concurrent communication capability (2) supporting QoS and mission-based communications. An efficient time synchronization scheme is also disclosed to ensure all beams can concurrently send data to the star node. Finally, ARMA or HMM based prediction schemes are disclosed to predict future traffic profile in each beam. This helps the star node to better prepare the queue content and schedule information.
