In this paper, we implement a Smart Mailbox using the Arduino and Bluetooth. Smart Mailbox alarm system was combining to the general mailbox. If a mail is arrived to the ultrasonic sensor mounted on the mailbox Smart Mailbox recognizes the mail and sends the smartphone data in real time through the Bluetooth module. Also it stores ultrasonic sensor data in Arduino when bluetooth communication is interrupted. Again it implemented a system for transferring the stored data when the bluetooth communication is made.

In this paper, we propose the access control system based bluetooth using the MAC address of the smart device. Access control system that propose compares the smart device MAC address entry and exit and MAC address that is registered with the server. Depending on whether the match was compared, access control is performed. Result of the experiment, control of door is possible only by bluetooth pairing of the bluetooth module and smart device. Therefore, it does not require access to another tool.In addition, Action for access approval is omitted. Therefore, the access authorization procedure is simplified compared to existing access control systems, it is possible to improve the convenience.

Bluetooth technology of cable replacement and infrastructure access is verified enough to be commercialized as goods. But there are a lot of works to implement ad-hoc Bluetooth radio network. for this, scatternet must be formed. We propose routing layer, packet format and link formation schemes for scatternet. The page procedure of the route request and the route reply page eliminates the procedure of the inquiry and the master-slave role switching. The route discovery time could be lower than 50msec within the distance of 50m. Proposed link formation scheme lets master, slave and bridge establish connection automatically and offers active ad-hoc environment. Devices that adopt Bluetooth module of 10m transmission range can communicate with other devices far away without any intervention of users.

According to a diversification of surveillance camera function, they have got to control the surveillance camera utilizing the controller or personal computer. The Method of solution is wired communications and wireless communications. But wired communications are a weak point because that need to use another cable and in case of communication system utilizing the Bluetooth universalized, there is the difficulty in the utility because electricity consumption is big. But the wireless communication utilizing the zigbee protocol is that electiricity consumption is more small than Bluetooth and reliability of data transmission is better. Therefore I designed system for control of surveillance camera with Zigbee protocol.

실내 위치 인식 기술은 여러 기술을 통해 시도되어 왔으며, 대표적인 기술로는 Wi-Fi 기반 위치 인식과 Bluetooth Low Energy 기반의 위치 인식이 있다. 하지만 Bluetooth Low Energy는 10m 거리 밖에선 오차가 많아지고 정밀도가 낮아지는 특성으로 인해 Wi-Fi가 보편화되었다. 본 논문에서는 핑거프린팅 기법을 이용하였을 때 Wi-Fi와 Bluetooth Low Energy의 위치 인식 기술의 성능 분석을 목적으로 기술되었다.

While researches and studies on short distance wireless communications have been actively carried out, studies on many applications of short distance wireless communications focusing on user-oriented Mobile device are also in progress. Since Bluetooth has several advantages that existing short distance communication does not have, studies on standardization have been carried out focusing on SIG, and IEEE has also jointly studied on this. Bluetooth is a short distance wireless communication technology that can be usefully applied to various kinds of applications. In this regard, this thesis presents payment system using Bluetooth, out of several application technologies of Bluetooth. This payment system is based on the scenario in which secure piconet is formed focusing on the user, the user gets in the car, fill up the gas at the gas station using his own Mobile device and pay The secure payment system presented in this thesis is designed to complement the weakness of existing Bluetooth in terms of security and to secure several requirements of security required for payment using short distance wireless communication.
