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
 

                    


In 2002-2004, the figure above reflected previous generations of mesh networking (single radio) versus our approach. But there was confusion about what "multi-radio" meant, and why Meshdynamics' patented 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

Topology: The toll cost and hop cost taught in this patent was applied to Pico nets. It was submitted to the IEEE 802.15.4 group on Ad hoc Mesh networking (as single radio meshed systems that tied into a two-radio Wi-Fi backhaul).

The hybrid mesh (below, developed for military) included both multi-radio backhauls and single radio meshed edge devices managed by a common mesh control layer. This distributed control and mediation layer was radio and protocol agnostic by design. It manages both network topology and timing etc to ensure the network is application aware. (See patents).
 

            

 

Terse Packets: Transporting Terse messages over IP presented challenges since IP backbones prefer largeackets and is best efforts based. No chirp devices existed at the time, so we modeled our notions of "Quasi-TDMA" using VOIP phones see:

Next, the Modular Mesh nodes needed mobility for our military and mining customers. See:

Disruption tolerance required fast switch over of tree-based routing tables to the new parents of trees and also self-tuning:
