Securing Wireless Bluetooth Sensor Systems

In this research paper a Low power, Portable and Secure Wireless Bluetooth Sensor System has been designed and its performance has been evaluated. The sensor system is light weight and has interoperability with Personal Area Network (PAN) and the architecture has been implemented by adopting an FPGA and a Bluetooth Module. The analysis of design shows its capability of continuous transmission of analog signals and a high rate of security level. As low sampling rates, the adopted solution offers low power consumption and lower battery capacity can be adopted and sensor weight can be minimized. With higher sampling rates, the Wireless Sensor System is equipped with FGMA which offers best architecture solution and high performance. So Wireless Bluetooth Sensor system can be widely adopted in critical applications like Detecting Vital Signs in Patients having serious pathologies.

INTRODUCTION Bluetooth, A technology which requires no introduction and is being used constantly in Mobile Phones, Computers, Tablet PC'S, TV'S, Gaming Consoles and much more for transferring the data from one device to another. Bluetooth Wireless technology is becoming very popular to replace existing short range wired technology with short-range Wireless technology to enable new types of applications. With the increase in use of Bluetooth Technology, Various Researches and Manufactures are closely working to use this technology in completely different environments such as in Medical sector to improve the life quality and to reduce the cost incurred by hospitals in treating patients. A new concept called PAN (Personal Area Network) is evolving along with Bluetooth Technology. A PAN consists of a limited number of units interconnected to form a network and to exchange information among the connected nodes. Bluetooth acts a local connection interface between different personal units like Mobile Phones, PDA's, Keyboard, Mouse, Gaming Consoles and much more. Bluetooth is a true enabling technology for the PAN Vision. The units are typically consumer devices which are used by different manufactures in different ways. So in order to have better interoperability between the personal devices, the security level has to be set up by the user. The Bluetooth technology has been designed in such a intelligent manner which enables even a ordinary user to maintain a good security level to protect the data and communication links in operation. With the help of PAN Technology, users can access their data wirelessly between different devices, work on them and store
