BLUETOOTH NETWORK TOPLOGY


Master Slave Concept
Master Controls All traffic in the Network

Piconet
It is Defined by its Frequency hopping Sequence

Scatternet


PICONET


One machine which is connected to one or more devices That type of connection is called Piconet

The Bluetooth piconet consists of 1 master device and up to 7 slave devices

Slaves cannot communicate directly with each other

Priority based scheduling

The master defines the priority in the piconet

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

Abstract
Bluetooth is a Radio Frequency specification for short-range, point-to-point and pointto- multi-point voice and data transfer. Bluetooth will enable users to connect to a wide range of computing and telecommunications devices without the need for proprietary cables that often fall short in terms of easy-to-use. The report examines what Bluetooth is, what it is good for and who is promoting it. The specification and profiles show how the technology works and how it is used -are reviewed. Competing and complementary technologies are di ....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

Abstract— Computational Private Information Retrieval (cPIR) protocols allow a client to retrieve one bit from a database, without the server inferring any information about the queried bit. These protocols are too costly in practice because they invoke complex arithmetic operations for every bit of the database. In this paper, we present pCloud, a distributed system that constitutes the first attempt toward practical cPIR. Our approach assumes a disk-based architecture that retrieves one page with a single query. Using a striping technique, ....etc
