Bluetooth enables portable electronic devices to communicate wirelessly via short-range ad-hoc networks. Initially Bluetooth will be used as a replacement for point-to-(multi)point cables. However, in due course, there will be a need for forming multihop ad-hoc networks over Bluetooth, referred to as scatternets. This paper investigates the capacity assignment problem in Bluetooth scatternets. ...

Key challenges in wireless mobile ad hoc networks are computational resource constraints, power limitations, and efficient service discovery techniques. The short range radio network technology Bluetooth suffers from long service discovery delays and high power consumption due to necessary connection establishment between discovering and discovered entity. For improving the efficiency of servic...

We discuss ways to enhance the location privacy of Bluetooth. The principal weakness of Bluetooth with respect to location privacy lies in its disclosure of a device’s permanent identifier, which makes location tracking easy. Bluetooth’s permanent identifier is often disclosed and it is also tightly integrated into lower layers of the Bluetooth stack, and hence susceptible to leakage. We survey...

Bluetooth has emerged as a viable COTS alternative for military applications involving low power wireless networks, including wireless sensor networks and personal area networks for the foot soldier. However, the reachability of Bluetooth networks is limited by the weak error control coding used by the predefined packets. In this paper, we propose a method for improving the performance of Bluet...

The BLUEPAC (BLUEtooth Public ACcess) concepts presented at LCN 1999 were ideas for enabling mobile Bluetooth devices to access local area networks in public areas, such as airports, train stations and super-markets. The proposed protocols support mobility on OSI layer 3. This paper concentrates on the necessary layer 2 protocol concepts for supporting mobility and handoffs between different ac...

As mobile operating systems reach the same level of complexity of computer operating systems, these may be affected by the same vulnerabilities and may be subject to the same kind of attacks. Bluetooth provides connectivity to a mobile phone but this network can also be used as a channel to deploy attacks and access its resources, such as personal information, confidential files or the possibil...

Each network device or portable device with HOST interface (radio or cable) has several hierarchical structures which distribute functionality between different layers of that device. The hierarchy defined radio interface, base band layer. During development of the Bluetooth module, a new complex architecture is integrated; it supports low cost upgrades related to new generations of Bluetooth d...

Bluetooth technology is specially designed for the wireless personal area networks to replace cable. Several challenges exist in Bluetooth scatternet formation and routing, since nodes can arrive and depart at arbitrary times. In this paper, novel route maintenance algorithms are proposed for the Bluetooth ad hoc networks, where nodes can enter or exit from the piconets time to time. Our protoc...

This paper describes a study of how 2.45GHz electromagnetic waves propagate indoors. 2.45GHz is a typical Bluetooth frequency. Propagation models with both one and several transmitters have been made using an advanced computer program. Furthermore, a model of the propagation of 433MHz radio waves has been made and used as a standard point of comparison. To make sure that such models are reliabl...

Data transmission over wireless networks is challenging due to the occurrence of burst errors, and packet loss caused by such errors seriously limits the maximum achievable throughput of wireless networks. To tailor efficient transmission schemes, it is essential to develop a wireless error model that can provide insight into the behavior of wireless transmissions. In this study, we investigate...
