Bluetooth Networking and its Security Architecture: Analytics of Network Concepts, Security Protocols, Vulnerabilities and Countermeasures

Bluetooth Networking and its Security Architecture: Analytics of Network Concepts, Security Protocols, Vulnerabilities and Countermeasures Review



Bluetooth wireless technology has become an essential part of our modern society. Mobile phones, game controllers, Personal Digital Assistant (PDAs), computers and various electronic gadgets have adapted Bluetooth and made it a popular technology for short range wireless communication. However, as the Bluetooth technology becomes widespread, it has shifted from short range and can now even have long range communication greater than WLANs with the help of extended antennas and so the vulnerabilities in its security protocols have also increased which can be potentially dangerous to the privacy of a user’s personal information. The security issues of Bluetooth has been an active area of research for the past few years. This book presents some vulnerabilities of this technology and proposes some countermeasures. It also provides some tips that end-users can implement immediately to become more cautious about their private information. A fairly new concept is also introduced in this book which uses a secure Bluetooth networking technology in a public environment to enable social networking between multiple users who do not have access to the internet.

Bluetooth Data Exchange over WLAN 802.11b: Analysis and Simulation: Bluetooth-WLAN Integrated Network

Bluetooth Data Exchange over WLAN 802.11b: Analysis and Simulation: Bluetooth-WLAN Integrated Network Review



The thesis focuses on studying of Bluetooth and WLAN technologies to establish Bluetooth – WLAN Integrated Network (BWIN). In particular, it addresses the problem of using WLAN coverage area to exchange data between two Bluetooth devices connected to different piconets. To achieve this goal the process of integration was studied taking in account number of factors: Interference, Noise, software development and incompatibility in packets length and addressing schemes. simulation frameworks developed to simulate the integration process and to give an analytical overview related differences between packets lengths, addressing schemes and modulation techniques used in both wireless technologies. Simulation frameworks also study the effect of Noise (AWGN) and interference in different locations in BWIN. Different issues arise when integrating between Bluetooth and WLAN networks relating to software development such as a piconet formation, performance evaluation and security requirements. These issues are studied and analyzed in this work.

Bluetooth Information Exchange Network: An approach to implement an indoor ad hoc multi-hop Bluetooth wireless network

Bluetooth Information Exchange Network: An approach to implement an indoor ad hoc multi-hop Bluetooth wireless network Review



Bluetooth is a low cost and low power wireless technology for connecting portable and / or fixed Bluetooth enabled devices to form short-range wireless ad hoc personal area networks (PANs). As the Bluetooth specification does not specify a protocol to form ad hoc Bluetooth networks, a method for forming an efficient Bluetooth network under a practical networking scenario is still an open research problem. This work introduces an approach to implement an indoor ad hoc Bluetooth wireless network, Bluetooth information exchange network (BIEN). A set of Bluetooth enabled devices are able to spontaneously establish a dynamic multi-hop wireless network using Bluetooth technology without the need of formal network infrastructure. This work is an attempt at implementation of a distributed multi-hop scatternet with an integrated routing in the practical environments, while most of the literature focuses on covering the modelling of it. It intends to demonstrate how Bluetooth technology with Java technology can be used to design, develop and deploy ad hoc wireless networks, and examine how well Bluetooth technology supports ad hoc multi-hop network technology.

A+, Network+, Security+ Exams in a Nutshell: A Desktop Quick Reference (In a Nutshell (O'Reilly))

A+, Network+, Security+ Exams in a Nutshell: A Desktop Quick Reference (In a Nutshell (O'Reilly)) Review



If you're preparing for the new CompTIA 2006 certification in A+, or the current Network+ and Security+ certifications, you'll find this book invaluable. It provides all the information you need to get ready for these exams, including the four new A+ exams -- the required Essentials exam and three elective exams that pertain to your area of specialization.

As with other O'Reilly Nutshell books for certification exams, A+, Network+ and Security + in a Nutshell follows a proven style and approach. It reviews all of the topics needed to master each exam in a remarkably concise format, with required knowledge boiled down to the core. Instead of plowing through 500 to 700 pages to prepare for each exam, this book covers each one in approximately 150 pages. And because the objectives for the three elective A+ exams are redundant, and the book covers them in one section.

The exams covered include:

  • A+ Essentials: Required for A+ 2006 certification
  • EXAM 220-602: For the A+ IT Technician specialization
  • EXAM 220-603: For the A+ Remote Support Technician specialization
  • EXAM 220-604: For the A+ IT Depot specialization
  • EXAM N10-003: For Network+ Certification
  • EXAM SYO-101: For Security+ Certification


Each exam is covered in three parts: Exam Overview, Study Guide and Prep and Practice. Plenty of detailed tables and screen shots are included, along with study notes and practice questions. Once you have completed the exams successfully, you will find this all-in-one book to be a valuable reference to core administration and security skills.
