RFID(Radio frequency indentification) technology, that the reader detect the tag information attached on the objects without contact, is considered the kernel of realizing tile Ubiquitous Sensor Network. Particularly, because there are lots of tags(which the reader have to detect) in the UHF RFID system(that is applied at the Logistic & Distribution industry). In the UHF RFID system the negative effects, we called the tag-collision, may occur and we should solve these effects. So, in the EPCglobal Gen2 protocol they present the Slotted Random Anti-collision algorithm to prevent the tag-collision effect. In this paper, in order to minimize the tag-collision effect and bring on the system efficiency, we propose the Power Increasing Method that controls the transmission power of the reader depending on the environment and verily the improved performance.

Recently the spread which RFID technology is overcomes the limit of existing recognition technology, it is forecast with the fact that it will bring a new renovation at the business and the industrial all over. Specially the case RFID technology of Port Logistic Industry will be applied it is forecast with the fact that it will bring a many effect. The government leads introduces a RFID technology of Port Logistic Industry through the various demonstration business. But it is many with the research insufficient the depression against an actuality improvement subject and the depression of technical know-how strategy and it is difficult it is undergoing. In order to solve this problems, we propose an introduction of technical know-how Road Map that we select ranking with Existing literature investigation and the present business demand anaylsis. In the future this research it it forecast in future the successful guide line to the RFID technology introduction of Port Logistic Industry will become.
