Key Intellectual Property

Meshdynamics' founder Francis previously started Advanced Cybernetics Group.  ACG was contracted by the US Air Force and NIST to work on Supervised Autonomy for remote robots (telerobotics). See Technical Paper.  When commercial radios became more affordable, ACG became Meshdynamics and we began work on robust real-time connectivity for remote military machines.

In 2002, SPAWAR and DARPA funded a multi-year NRE contract for us to develop a distributed, fault-tolerant device/protocol agnostic mesh control layer for use on military gear. This includes Non-IP based stealth “sensor dust”. Our solution must support real time, terse, Non-IP “Stealth Chirps” securely over IP backbones.

Taking cues from Nature, our work began with tree-based control networks then moved to ants (mobility), pollen (broadcast storms for propagation) and finally birds (Chirp and Chirp protocols).  The following condensed history reflects the progression and the extensions to this protocol and device agnostic distributed mesh control layer we refer to as MeshControlTM z
 

                    


Tree Based Backhaul  In 2002-2004, the figure above reflected previous generations of mesh networking (single radio) versus our approach. But there was confusion about what "Dual-radio" meant, and why our tree-based framework set us apart.

This performance analysis was first published on our website. Soon others were also selling two radio backhaul mesh nodes.

This mother patent refers to our novel tree-based mesh approach

The hybrid mesh (below) included both multi-radio backhauls and single radio meshed edge devices managed by a common mesh control layer that sat above the MAC/PHY but had real time kernel extensions see above. This distributed control and mediation layer was radio and protocol agnostic by design- our licensee take our prototype software and port it to run on their devices. This layer manages both network topology and timing etc to ensure the network is application aware. (See patents).
 

  


Terse Packet Transport IP backbones prefer large packets and best efforts - everything else costs extra. No chirp devices existed at the time, so we modeled our notions of  collaboratively scheduled "Chirp" bus shuttles with VOIP packets.
