Abstract

The Bluetooth technology is the convergence of Mobile Co mmun ication and Co mputing Applications. The set of Mobile Devices Laptops, Notebook Co mputers,PDA's,Mobile Smart Phones etc connected by Bluetooth protocol forms a Bluetooth Network or Bluetooth Piconet or WPAN.Even through the devices have numerous benefits its open nature increases the threats and risks being posed on them. The wired network faces challenging problems because of internet worms , similiarly the Bluetooth Network or WPAN faces serious problems because of Bluetooth Worms. This paper gives a comparative study of WPAN performance on impact of Bluetooth Worms in Bluetooth Piconet (symmetric) and Bluetooth Piconet(asymmetric) and derives the result how the degree of homogeneity increases the infection rate.

Highlights

Bluetooth technology is the low power, low cost technology used in short range radiofrequency (RF) communicat ion
Bluetooth is designed to run in a peer to peer short range wireless network
In all the cases the infection rate is higher for symmetric Piconets .The above results derive that Wireless Personal Area Network (WPAN) having similar devices are are prone to have higher degree of attack as well as degradation of QOS

Summary

Bluetooth Technolog y

Bluetooth technology is the low power, low cost technology used in short range radiofrequency (RF) communicat ion. It is a protocol used for connecting a set of wireless devices, ranging fro m PDAs, Smart phones , Notebook computers, Laptops etc,. In point to multipoint connection , the channel is shared among several Bluetooth devices. Two or more devices sharing the same channel fo rms a piconet[Figure1]and multip le piconets with overlapping coverage area forms a scatternet. A device wh ich is a member in more that one Piconet is called bridge. Sect ion 2 focuses on Bluetooth Secu rity issues. Sect ion 3 d iscuss on t raffic scheduling algorith m to evaluate QOS in the piconet and
