Dragging the world towards wireless galaxy

Various sensors are already in a broad use today as part of different devices or as standalone devices connected to a network usually to monitor industrial processes, equipments or installations.

The advancements in technology, wireless communications have enhanced development of small, low power and low cost devices. Such devices when organized into a network, present a powerful platform that can be used in many interesting applications. Bluetooth is a low cost, short-range, wireless technology ....etc

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 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

Every new invention in the past ha to contend with various cynics who content that the existing technology is better than the new one or do you recall anyone saying That wonâ„¢t work man itâ„¢s too Hi-Fi, Well Blue tooth is also passing through the same phase.

For every new technology to get integrated into the society we have to pass certain phases that are predefined.

1. Scientific discussion: This is the place where the new technology is introduced and born out. Here the papers are presented at scientific seminars. Various pr ....etc

Bluetooth is one of the most recent development in wireless technology. Bluetooth technology allows wireless connection between various communication devices with ease. The paper begins with a brief introduction of Bluetooth technology and the need for it. It then explains other two types of wireless communication viz. Infrared communication and Cable Synchronization and the advantages of Bluetooth over these. It also explains the techniques by which Bluetooth avoids interference from other electronic devices. Further an example is illustrated ....etc
