摘要

The present invention relates to a distributed parallel processing-based ubiquitous sensor network load (workload) simulator system and a simulation method using the same, and specifically, it is constantly measured in real time in a ubiquitous sensor network (USN) in which wired and wireless are combined. Distributed, invented to produce the same effect as receiving and transmitting data by simulating it to the actual situation, and supplying data by connecting or processing a system that uses or processes them to the actual ubiquitous sensor network system. It relates to a simulation system using a parallel computing technique and a simulation system and method using the same. To this end, the present invention collects the values transmitted from the USN simulation master, the USN simulation worker simulating each USN, and each USN simulation worker, which conducts the simulation collectively, processes it internally, and processes it in the sensor data processing system. Provided is a ubiquitous sensor network simulator using the distributed parallel computing technique, which includes a sensor data collector that transmits when requested. The ubiquitous sensor network simulator using the distributed parallel computing technique, A comprehensive simulation plan is constructed and managed and supervised by the USN simulation master; The global simulation plan constructed by the USN simulation master is executed by the USN simulation worker under the command and control of the USN simulation master, and a distributed computer performs a single worker, and multiple distributed computers are distributed in parallel. It is possible to process, and distributed parallel processing using multiple distributed computers is possible as one distributed computer is performed by multiple workers, and one sensor network can be allocated from multiple workers, and can be processed by multiple workers. It is possible to assign a sensor network and it is possible to assign a plurality of sensor networks to a plurality of workers; A distributed parallel computing method that performs the steps of simulating, generating, and processing the data generated by the USN simulation worker and transmitting the sensor data collector to the sensor data processing system when the sensor data processing system needs it. Provides a method and system for simulating ubiquitous sensor networks using. Therefore, according to the present invention, the sensor data processing system is operated using the USN simulator without actually connecting to the USN. Data having the same characteristics as data transmitted from the actual USN can be supplied freely without connecting to the USN.
