Abstract

Bluetooth has been developed to be applied over the course of several versions in different environments. Especially low is moving to address the constraints, it gives a high utilization rate is faster than the Zigbee wireless LAN communication. To gather information on children's environmental copper transition to multiple versions. There is one limitation of Bluetooth requirements to effectively apply the information collected by Bluetooth. At the same time need to collect several information actions, Bluetooth can not connect to one of only seven Slave Master. In this paper, in order to take advantage of the many benefits of Bluetooth to gather the information by operating the Bluetooth operates in Beacon deliver packets of 168 bits, and the pairing between the master and slave unnecessarily generate a regular signal a large number of connections simultaneously Information We consider how to apply the effective policy that can be collected.

근거리 무선통신으로 Bluetooth, Zigbee와 Wi-Fi가 요즘 들어 많이 사용되고 있다 . 성능이 우수하나 자주 전력공급으로 보조 전원장치가 있어야 되는 Wi-Fi가 있는 반면, 속도등의 성능은 떨어지나 저전력으로 전원장치가 작아 휴대성이 간편한 Bluetooth와 Zigbee가 있다. Bluetooth의 버전은 1.0부터 4.2까지 여러 환경에 적용하기 위해 변천해왔다. 어린이 동선 환경 정보를 수집하기 위해 여러 버전으로 변천해 온 Bluetooth로 정보 수집을 효과적으로 적용하는데 제한 요건으로 한 명이 아닌 여러 명의 동선 정보를 동시에 수집해야 하는데 Bluetooth는 Master 하나당 7개의 Slave만 동시에 접속 할 수밖에 없다. Bluetooth의 여러 장점을 활용하여 동시에 7개 이상의 정보를 수집하기 위해 본 논문에서는 Bluetooth 동작을 Beacon으로 동작시켜 168비트의 패킷을 전달하며 주기적신호를 발생하여 master와 slave간 페어링이 불필요하게 하여 동시에 많은 수가 접속하여 정보를 수집할 수 있는 효과적인 정책을 적용하는 방법을 설계한다.
