How propagator nodes will work in communicating devices in IOT: As noted previously, replicating even this highly efficient chirp protocol traffic indiscriminately throughout the IoT would clearly choke the network, so intelligence must be applied at levels above the individual end devices. This is the responsibility of propagator nodes, which are devices that create an overarching network topology to organize the sea of machine-to-machine interactions that make up the Internet of Things. Propagator nodes are typically a combination of hardware and software distantly similar to WiFi access points. They handle "local" end devices, meaning that they interact with end devices essentially within the (usually) wireless transmission range of the propagator node. They can be specialized or used to receive chirps from a wide array of end devices. Eventually, there would be tens or perhaps hundreds of thousands of propagator nodes in a city like Las Vegas.  Propagator nodes wi...
