Apparatus and system for managing a sensor network

A network system, comprising:

• a device management (DM) server configured to send a DM command for managing a sensor network topology;
• and
• a Machine to Machine (M2M) gateway coupled to the DM server and to a plurality of sensor devices in a sensor network, the M2M gateway being configured to:
• store a topology tree that includes first and second management object (MO) nodes, wherein the first MO node includes an identification and a type of the sensor network and the second MO node describes a characteristic of each of the plurality of sensor devices and a connection relationship of the plurality of sensor devices, wherein the topology tree corresponds to the sensor network topology;
• after receiving the DM command and according to address information of the second MO node within the DM command, retrieve the characteristic of each of the plurality of sensor devices and the connection relationship of the plurality of sensor devices from the second MO node;
• and
• send the characteristic of each of the plurality of sensor devices and the connection relationship of the plurality of sensor devices of the sensor network to the DM server.

A method for remotely managing a sensor network topology, comprising:

• receiving, by a Machine to Machine (M2M) gateway, a device management (DM) command for remotely managing a sensor network topology from a DM server that connects to a plurality of sensor devices within a sensor network via the M2M gateway;
• wherein, the M2M gateway stores a topology tree that comprises first and second management object (MO) nodes, the first MO node comprises an identification and a type of the sensor network and the second MO node describes a characteristic of each of the plurality of sensor devices and a connection relationship of the plurality of sensor devices, wherein the topology tree corresponds to the sensor network topology;
• after receiving the DM command and based on address information of the second MO node within the DM command, retrieving, by the M2M gateway, the characteristic of each of the plurality of sensor devices and the connection relationship of the plurality of sensor devices from the second MO node in the topology tree;
• and
• sending, by the M2M gateway, the characteristics of each of the plurality of sensor devices and the connection relationship of the plurality of sensor devices of the sensor network to the DM server.
