Abstract
A network node for monitoring a mobile asset in a geographical area. The network node is among a number of network nodes disposed in the geographical area that are configured to receive an Internet-of-things (IoT) signal from the mobile asset, and send respective time stamps, each representing a time-of-arrival (TOA) of the IoT signal, to a network aggregation system to generate a time-difference-of-arrival (TDOA) from which a geolocation of the mobile asset is generated.
