Among the optimization method, GA (genetic algorithm) is a very powerful searching method enough to compete with design sensitivity analysis method. GA is very easy to apply, since it dose not require any design sensitivity information. However, GA has been computationally not efficient due to huge repetitive computation. In this study, parallel computation is adopted to Improve computational efficiency, Paralleled GA is introduced on a clustered LINUX based personal computer system.

What Ubiquitous means "being or existing anywhere, anytime"in Latin, which is, in other words, the users are able to access the network no matter where they are, what kind of network or computer terminals they use. This paper focuses on the implementation of hardware system. The first part of the sytem is the sensor node which transmits the sensor data from node to ARM11 platform through the Zigbee network wirelessly. The other part of the system is the ARM11 platform which receives and displays the sensor data. ARM11 platform is sink node. The ARM11 platform is based on ARM11 architecture and ported with Linux OS. Qtopia is used as Window Manager in order to make applications. The highly efficient ARM11 processor, S3C6400 MPC is the main part of the ARM11 platform.
