1 is a flow chart provided to explain a method of monitoring an unmanned mobile network according to an embodiment of the present invention.

In order to monitor the topology and communication of the unmanned mobile network, first, a management resource is configured by collecting status information of unmanned mobile vehicles constituting the network (S110).

The state information collected in step S110 includes neighboring node information, routing information, and location information of the unmanned mobile vehicle.

2 is a diagram illustrating a configurable topology management resource in step S110. As shown in FIG. 2, the topology management resources include network resources, unmanned mobile vehicles constituting the network, and GCS (Ground Control Station) resources, and their status information resources.

Next, a topology of an unmanned mobile network is configured from the state information collected in step S110 (S120). Specifically, in step S120, a network topology is constructed from connection information of unmanned mobile devices.

Network topologies configured in step S120 are illustrated in FIGS. 3 and 4, respectively.

The topology illustrated in FIG. 3 is a topology of a GCS-centered data transmission structure, where the GCS collects state information of unmanned mobile vehicles (UAVs) and delivers them to the Mobius system corresponding to the M2M platform.

The topology illustrated in FIG. 4 is a topology of a distributed data transmission structure, and is a topology of a network in which GCS and unmanned mobile vehicles directly transmit their state information to the Mobius system.

Next, a location-based network topology is generated by reflecting the location information of the unmanned moving objects in the network topology configured in step S120 (S130).

In reflecting the location information, a two-dimensional topology can be formed by reflecting the two-dimensional location information of the unmanned moving objects, and a three-dimensional topology can be constructed by reflecting the three-dimensional location information of the unmanned moving objects.

Two-dimensional location information includes (latitude, longitude), and three-dimensional location information includes (latitude, longitude, altitude).

Thereafter, the topology of the unmanned mobile network generated in step S130 is matched with the map to be visualized (S140). The unmanned mobile network topology screens visualized in step S140 are illustrated in FIGS. 5 and 6, respectively.

The screen illustrated in FIG. 5 is a screen in which a network topology implemented in a two-dimensional shape is matched to a two-dimensional map, and the screen illustrated in FIG. 6 is a screen in which a network topology implemented in a three-dimensional shape is matched to a three-dimensional map.

In addition, in an area of the topology visualization screen of the unmanned mobile network, the unmanned mobile objects constituting the network topology are listed (S150). When the user selects one of the listed unmanned moving objects, the selected unmanned moving object is highlighted on the topology and displayed (S160).

As illustrated in FIGS. 5 and 6, it can be seen that unmanned moving objects constituting the network are arranged in the left area of the topology screen. Among the listed unmanned moving objects, the unmanned moving object selected by the user may be displayed by highlighting it on the topology.

Further, for the selected unmanned moving object, status information can be displayed, and other information other than the above-described status information can be further included.

In addition, if two unmanned vehicles are selected, routing information between them may be displayed on the network topology.

The M2M system according to an embodiment of the present invention may be implemented as a computing system including a communication unit 210, a processor 220, and a storage unit 230, as shown in FIG. 7.

The communication unit 210 communicates with nodes constituting an unmanned mobile network to collect status information, and provides a service by communicating with a user terminal that wants to monitor the network.

The processor 220 performs the monitoring process shown in FIG. 1 and provides the execution result to the user terminal.

The storage unit 230 provides a storage space necessary for the above-described management resource to be built and the processor 220 to operate.
