ACG was contracted by the US Air Force
and NIST to work on Supervised Autonomy for remote robots (telerobotics). See
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
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

The hybrid mesh (below) included both multi-radio backhauls and
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).

backbones prefer large packets and best efforts - everything else costs
extra. No chirp devices existed at the time, so we modeled our notions of
