Abstract

Provided are a system and a method for controlling a network configuration for a moving object. A monitoring device attached to the moving object, that is, a container loading a cargo, recognizes loading and moving circumstances of the container, construct a network with other containers according to the circumstances and performs connection/disconnection of the container to/from a network and maintenance of the connection until the container departs the origin and arrives at a destination through overland transportation and marine transportation. Accordingly, the state of the container is monitored, monitoring information is transmitted to a container administrator and the power of the monitoring device which constructs an optimized network with other monitoring devices according to container circumstances is saved.
