Hereinafter, the preferable embodiments of the present invention will be described in detail with reference to the attached drawings. The same reference numerals shown in each drawing indicate the same elements.
FIG. 1 is a block diagram illustrating a ubiquitous monitoring system 100 according to an embodiment of the present invention.
Referring to FIG. 1, the system 100 includes a plurality of sensing nodes APP1 to APPn, EQ1 to EQn, and SW1 to SWn, one or more monitoring agents 120_1 to 120—n, a monitoring module 140, an analysis module 150, a database 160, and a monitoring viewer 180.
The plurality of sensing nodes APP1 to APPn, EQ1 to EQn, and SW1 to SWn are installed in a ubiquitous space, sense various data generated in the ubiquitous space, and transmit sensing data to the monitoring agents 120_1 to 120—n. 
For example, the sensing nodes APP1 to APPn may be various applications executed in the ubiquitous space, the sensing nodes EQ1 to EQn may be various devices belonging to the ubiquitous space, and the sensing nodes SW1 to SWn may be various software executed in the ubiquitous space. The sensing nodes APP1 to APPn, EQ1 to EQn, and SW1 to SWn may sense and transmit hardware data such as a rate of using a CPU, a status of using a memory, and a residual amount of a battery, to the monitoring agents 120_1 to 120—n. Also, the sensing nodes APP1 to APPn, EQ1 to EQn, and SW1 to SWn may sense and transmit software data such as thread information, a message transmission status, and a status of procedure, to the monitoring agents 120_1 to 120—n. 
The one or more monitoring agents 120_1 to 120—n receive and transmit sensing data of the sensing nodes APP1 to APPn, EQ1 to EQn, and SW1 to SWn, to the monitoring module 140.
The monitoring module 140 collects sensing data from the one or more monitoring agents 120_1 to 120—n and manages the sensing data for each type and time. The monitoring module 140 may modify formats of the collected sensing data into a data format capable of being recognized by the analysis module 150.
The analysis module 150 deduces function information, performance information, and status information for each of smart objects, based on sensing data. The analysis module 150 deduces function information, performance information, and status information on a ubiquitous service executed by coupled smart objects, based on the information for each of the smart objects. The analysis module 150 transmits a result of deduction to the monitoring viewer 180.
The monitoring viewer 180 displays the result of deduction to a user.
The monitoring module 140, the analysis module 150, and the monitoring viewer 180 may store operation logs, collected sensing data, and a result of deduction in the database 160.
FIG. 2 is a block diagram illustrating the monitoring module 140 and the analysis module 150 in detail.
Referring to FIG. 2, the monitoring module 140 may include a sensing data receiving unit 141, an emergency buffer 142, a field buffer 143, a module method buffer 144, a resource buffer 145, a system resource buffer 146, and a data wrapper 147.
The sensing data receiving unit 141 receives sensing data from the monitoring agent 120_1. The emergency buffer 142 processes sensing data to be emergently monitored. The field buffer 143 monitors function and performance of a ubiquitous intelligent object, which is remote-executed. The module method buffer 144 monitors a status of executing a method in a ubiquitous intelligent object service module. The resource buffer 145 analyzes statuses of a CPU and a memory of the ubiquitous intelligent object service module in real time. The system resource buffer 146 analyzes a status of a resource of a host where the ubiquitous intelligent object service module is used, and a status of a resource of the system 100 where the ubiquitous intelligent object service module is included. The data wrapper 147 collects and transmits processing results of the emergency buffer 142, the field buffer 143, the module method buffer 144, the resource buffer 145, and the system resource buffer 146, to the analysis module 150.
Referring to FIG. 2, the analysis module 150 may include a collector 151, a knowledge base providing unit 152, an estimation processing unit 153, a service use degree measurement unit 154, a user satisfaction index measurement unit 155, a resource use degree measurement unit 156, and an event generating unit 157.
The collector 151 collects one of sensing data and processing results from the monitoring module 140. The knowledge base providing unit 152 stores the sensing data and the processing results from the collector 151. The estimation processing 153 transmits one of sensing data and processing results of the knowledge base providing unit 152 to the service use degree measurement unit 154, the user satisfaction index measurement unit 155, and the resource use degree measurement unit 156.
The service use degree measurement unit 154 measures a degree of use of a user with respect to a ubiquitous service formed of ubiquitous community. The user satisfaction index measurement unit 155 measures a degree of satisfaction of a user as an index, by reflecting variances of various indexes of a ubiquitous service. The resource use degree measurement unit 156 measures a degree of using resources according to providing a ubiquitous service. The service use degree measurement unit 154, the user satisfaction index measurement unit 155, and the resource use degree measurement unit 156 may operate based on the knowledge base providing unit 152. As described above, the analysis module 150 may deduce high-level monitoring factors by integrating and analyzing various monitoring information based on knowledge.
The event generating unit 157 generates events on measurement results of the service use degree measurement unit 154, the user satisfaction index measurement unit 155, and the resource use degree measurement unit 156.
FIG. 3 is a diagram illustrating layered information of the system 100.
Referring to FIG. 3, first level information may be sensing data sensed by the sensing nodes APP_1 to APP_n, EQ1 to EQn, and SW1 to SWn. Second level information may be information on each of smart objects, which is generated by the analysis module 150, based on sensing data. Third level information may be information on a ubiquitous service, which is generated by the analysis module 150, based on information on each of smart objects. In this case, upper level information may be generated based on lower level information. For example, the third level information may be generated based on the second level information, and the second level information may be generated based on the first level information.
As described above, the system 100 may deduce and generate information on smart objects and information on a ubiquitous service, based on sensing data. Accordingly, statuses of various smart objects in a ubiquitous space may be monitored in real time, and a level of a ubiquitous service may be analyzed and estimated. Also, it is possible to integrally monitor various smart objects in a ubiquitous space. Also, it is possible to provide adaptable services to users in a dynamic environment by analyzing and applying sensing data from the monitoring module 140 and to provide an environment for self-restoration when there is generated interruption or malfunction in the system 100.
The analysis module 150 may determine whether to deduce both of the second level information and the third level information, to deduce only the second level information, or to deduce neither of the second level information and the third level information.
As described above, exemplary embodiments have been shown and described. Though specific terms are used herein, they are just used for describing the present invention but do not limit the meanings and the scope of the present invention disclosed in the claims. Therefore, it would be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention.
