Apparatus and method for testing a target sensor node for constructing a sensor network {Method and Apparatus for Testing Target Sensor Node to compose Sensor Network}

The present invention relates to an apparatus and method for testing a target sensor node for constructing a sensor network, and more particularly, to a sensor for testing a target sensor node without building an actual sensor network in a sensor network environment consisting of several sensor nodes. An apparatus and method for testing a target sensor node for constructing a network is provided.

The present invention is derived from the research conducted as part of the IT growth engine technology development project of the Ministry of Information and Communication and the Ministry of Information and Telecommunication Research and Development. [Task Management No .: 2006-S-085-01, Title: Development of an ultra-small operating system for automotive sensor nodes Nano OS for Automobile Sensor Nodes].

In general, a network consisting of a network of low-cost, ultra-small sensors is called a sensor network. Sensor network is used for ecological environment monitoring, intelligent environment monitoring, location recognition service, intelligent medical system, intelligent robot system, etc., and is developing as a core technology of ubiquitous computing environment.

The conventional sensor network is tested before configuring the network with each sensor node. If the sensor node cannot be directly controlled according to the characteristics of the sensor node, the sensor network is composed of a remote test environment consisting of a host and a target. Doing. Also, because sensor nodes are not used individually but as part of a network, testing with only a single node separated can cause a number of side problems. In addition, in order to test a target sensor node used in a large sensor network, it is expensive and time consuming to construct a sensor network, and in order to operate a large sensor network, a large number of sensors must be stimulated and generated accordingly. It is a very inefficient way to analyze the network and receive and process the results.

In addition, unlike general computer network systems, sensor network systems are designed to have a specific response or processing to a user or external input. In other words, each sensor that performs logically defined functions in the network must be correctly performed according to the intended order and procedure, and satisfies the condition that the performance of the functions must be performed correctly despite external interference and interference due to the characteristics of the sensor network. You have to. Such a sensor network system is developed in a different way from a general computer network, and it is very difficult to develop a reliable sensor network system because much knowledge about the sensor network is required besides software. Therefore, in order to stably develop such a high-fidelity sensor network system, there is an increasing need for a method for effectively testing a function reflecting various needs according to characteristics of a sensor network, finding a problem, and correcting it.

However, when testing using a hardware device, testing on a single target node is possible, but it is impossible to test various types of events that can occur under the sensor network environment. It is used to determine whether or not. In addition, when using a simulator, a virtual sensor node can be created and tested after constructing a network, so it is a way to test various events occurring in a network environment, but it solves problems that may occur when interfacing with a real target sensor node. It can only find problems that occur in virtual environments.

Therefore, the above solution cannot identify various problems that occur when the actual target sensor node operates in the sensor network environment. Therefore, the target sensor nodes necessary for network construction are clearly tested and the problems that occur accordingly are found. There is a strong need for technology.

Hereinafter, a sensor node test automation method using an apparatus for testing a sensor node according to the present invention will be described with reference to the drawings.

4 is a flowchart illustrating a method of testing a target sensor node for constructing a sensor network according to the present invention. In the description, the same reference numerals as in FIGS. 1 to 3 refer to performing the same function.

Referring to FIG. 4, first, configuration information about another node in the sensor network in which the target sensor node 10 is configured through the user interface 400 is received, and a virtual node is selected based on the configuration information about the other node. The virtual sensor network 210 is configured by creating and connecting the configured virtual node and the target sensor node. Subsequently, the automatic sensor node tester tests the virtual sensor network 210 composed of the virtual sensor network 210 and the target sensor node 10 according to the command input to the user interface 400.

In detail, the virtual sensor network manager 200 generates virtual nodes 211a, 211b, 211c, ..., 211n for the sensor network to which the target sensor node 10 is to be applied (S10).

At this time, the user interface 400 generates various types of nodes required for the sensor network according to the input configuration information, and sets and generates characteristics and roles of each node.

Subsequently, the automatic sensor node tester 300 connects the actual target sensor node 10 to be tested with the virtual nodes 211a, 211b, 211c, ..., 211n (S20).

Here, the target sensor node 10 is connected to the automatic sensor node tester 300 through a physical channel, and is a real sensor node including all the software and hardware required for the sensor node.

Next, the virtual sensor network 210 is constructed by including the virtual sensor nodes generated through the sensor node automatic tester 300 and the sensor network manager 200 and the actual target sensor node 10 (S30).

Here, in order to construct the virtual sensor network 210, an event required for the sensor network and information to be acquired must be received through the user interface 400, which is a virtual sensor network (the virtual sensor network controller 250). An event necessary for the control of the controller 210 and the control of the actual target sensor node 10 by the sensor node controller 330 is changed and stored in the event store 360.

Thereafter, the command is received from the user through the user interface 400 and interpreted by the user command interpreter 390 of the automatic sensor node tester 300 (S40).

Here, the command input by the user is divided into a virtual sensor network control command, a target sensor node automatic test command, and a target sensor node control command, and may perform an appropriate action for each command.

If the command interpreted by the user command interpreter 390 in step S40 is a virtual sensor network control command, the event generator 350 generates an event and transmits the event to the virtual sensor network 210 through the event interpreter 320. An event corresponding to the command is generated (S50) and transmitted (S55).

That is, when the event generator 350 generates an event for controlling the virtual sensor network 210 according to the command interpreted by the user command interpreter 390 and interprets the event in the event interpreter 320, the virtual sensor network manager 200. Send the appropriate command.

At this time, an event corresponding to a command interpreted by the user command interpreter 390 is generated. When an external input or environment change occurs in the actual sensor network, an error in data transmission in the actual sensor network, a specific node These are situations that can occur in a real sensor network, such as a failure of a sensor. This actual situation is mapped to each event and stored in the event store, and the stored event can be added, deleted, and modified.

If the command interpreted in step S40 is a target sensor node automatic test command, the test case is interpreted to generate a test case (S60), and the target sensor node 10 is tested based on the case (S65).

Here, the user command interpreter 390 in the sensor node automatic tester 300 delivers the user's test command to the test case generator 370 to generate a test case for the automatic test and store it in the test case repository 380. . The test case interpreter 340 interprets the stored test case and generates an event required for the test through the event generator 350 to allow the sensor node controller 330 to control the target sensor node 10 or the virtual sensor network interlocker. The virtual sensor network 210 may be controlled through the 310.

If the command interpreted in step S40 is a target sensor node control command, the sensor node automatic tester 300 interprets it and generates and transmits an event corresponding to the user's command to the target sensor node 10 (S70). (S75).

That is, the user command interpreter 390 generates an event for the control of the target sensor node 10 through the event generator 350, and transmits the generated event to the sensor node controller 330 to actually output the target sensor node 10. Can be operated.

Next, the execution result generated in steps S55, S65, and S75 is transmitted to the user (S80).

That is, the results processed in steps S55, S65, and S75 are transmitted to the user command interpreter 390 through the event interpreter 320 and the test case interpreter 340, and the delivered results are provided to the user through the user interface 400. can do.

Finally, it is determined whether another command is input from the user through the user interface 400, and the above steps S40 to S80 are repeated to process the user's command (S90).

For example, when a user command input to the user interface 400 changes, that is, when the user changes an input value through another user command to change the environment to be tested, the sensor node automatic tester 300 may change the user command. The command event is transmitted to the target sensor node 10. The target sensor node receives the transmitted result and operates according to the stored program and sends the result, and the result is used as an input of the virtual sensor network 210 to operate the virtual sensor network 210 and the result. To the user through the user interface 400 again. According to this procedure, the user can test the target sensor node by making a desired operation virtually, and store it as a test case in the next test to be automatically performed by the automatic sensor node tester 300 according to the present invention. . In addition, the user may make a desired change to the virtual sensor network 210 and have the target sensor node 10 receive and process the result.

As described above, the user can finally test the target sensor node 10 belonging to the virtual sensor network automatically, find a problem, and correct an error.

Accordingly, the present invention can test the actual target sensor node as if it is included in the established sensor network through the sensor node test automation device in the host system, and thereby find and correct a problem.
