1. An apparatus for controlling a backbone network for a sensor network, the apparatus comprising:

  • a context interpreter for interpreting a service request requesting a service to a sensor node, received from a user according to the type of the service request and generating a session comprising routing information about the interpreted service request;

    a sensor node register for storing sensor node information and routing information about sensor nodes registered to the backbone network and, upon receipt of the service request, providing routing information corresponding to the service request to the context interpreter;

    a gateway for transmitting the service request to the sensor node registered to the backbone network and receiving a response message to the service request from the registered sensor node; and

    a message processor for transmitting the service request received from the context interpreter to the gateway through the generated session and providing the response message received from the gateway to the user; and

    a sensor node authenticator for pre-storing information about sensor nodes that are accessible to the backbone network,wherein if the sensor node accesses the backbone network for registration, the sensor node register determines whether to allow the sensor node to access the backbone network by asking the sensor node authenticator whether the sensor node is authorized to access the backbone network,wherein if the sensor node without a backbone network ID accesses the backbone network for registration, the sensor node register receives an authentication request for the backbone network, comprising a unique Identifier (ID) of the sensor node, through the gateway, stores association information between the sensor node and the gateway, determines whether the unique ID of the sensor node exists in the sensor node authenticator by asking the sensor node authenticator about the unique ID of the sensor node, allocating the backbone network ID to the sensor node in the presence of the unique ID of the sensor node in the sensor node authenticator, registers the sensor node by storing the backbone network ID mapped to the association information between the sensor node and the gateway, and transmits the backbone network ID to the sensor node through the gateway.
