Bluetooth wireless technology is a cable replacement technology that provides wireless communication between portable devices, desktop devices and peripherals. It is used to swap data and synchronize files between devices without having to connect each other with cable. The wireless page link has a range of 10m which offers the user mobility. This technology can be used to make wireless data connection to conventional local area networks (LAN) through an access point. There is no need for the user to open an application or press but ....etc

The communications capability of devices and continuous transparent information routes are indispensable components of future oriented automation concepts. Communication is increasing rapidly in industrial environment even at field level.In any industry the process can be realized through sensors and can be controlled through actuators. The process is monitored on the central control room by getting signals through a pair of wires from each field device in Distributed Control Systems (DCS).

Bluetooth Security

Abstract :

Bluetooth is a way of connecting machines to each other without cables or any other physical medium. It uses radio waves to transfer information, so it is very easily affected by attacks. In this let me first give some background information about Bluetooth system and security issues in ad hoc networks, a security framework is introduced for the description of the Bluetooth security layout.
Then both link-level and service-level security schemes are discussed in detail on the basis of the framework and then ....etc

Bluetooth is the name given to a technology standard using short-range radio links, intended to replace the cable(s) connecting portable and/or fixed electronic devices. The standard defines a uniform structure for a wide range of devices to communicate with each other, with minimal user effort. Its key features are robustness, low complexity, low power and low cost, which make it especially suited to mobile handheld devices. The technology also offers wireless access to LANs, PSTN, the mobile phone network and the Internet for a host of home a ....etc

Bluetooth Ad Hoc Networking

Abstract :

Bluetooth is an open specification for short-range wireless communication and networking mainly intended to be a cable replacement between portable and/or fixed electronic devices. The problem concerns the assignment of the roles of master and slave to each node so that the resulting MANET is connected. In this Seminar we have introduce two novel protocols for forming connected scatternets. In both cases, the resulting topology is termed a bluetree. We also address the problem of determining an opt ....etc

ABSTRACT
The aim of this paper is to describe the implementation of a lowpower,low-cost 16-bit RISC microcontroller that will act as thecore of a stand-alone security system. The controller is designedto provide moderate-high security at very low cost and to be ableto operate independent of a database. It is designed using 1.5-mSCMOS process from MOSIS and operates at a frequency of 12.5MHz.

Multipliers are among the fundamental components of many digital systems
The largest contribution to the total power consumption in the multiplier is due to the generation of partial product
Among all the multipliers shift and add multipliers are the most commonly used ,due to its simplicity & relatively small area requirement
