Abstract

A wireless data communications network system for establishing communication between a server and a plurality of containers that are loaded onto a cargo vessel. The system includes a data communications device configured to establish and manage a pre-configured wireless data communications network and to communicate with the server through a local area network, and a plurality of electronic tracking devices each having a wireless transceiver and routing capabilities and configured to be joined to a container and to connect to the wireless data communications network upon being activated. The data communications device is configured to intermittently perform a network scan to locate each tracking device connected to the network and reconfigure the network topology to include each connected tracking devices such that the data communications device maintains mutual communication with each connected tracking device using the routing capabilities of the tracking devices.
