Analysis of UDP Performance over Bluetooth

The Bluetooth protocol is one of the better-known technologies in the field of pervasive computing and is now beginning to emerge in the consumer electronics marketplace in devices such as digital cameras, mobile phones and laptops. This paper examines the performance of the Bluetooth protocol using a simulator developed as part of the University of Berkeley’s Network Simulator (ns) [1]. In par...

Rendezvous scheduling in Bluetooth scatternets

Bluetooth scatternets are formed by interconnecting Bluetooth piconets in an ad-hoc fashion and consists typically of the handheld electronic devices from one or more user(s). Thus, scatternets may be used to form and interconnect adhoc Bluetooth personal area networks (PANs). The inter-piconet Bluetooth units, i.e. the gateways interconnecting the piconets in a scatternet, need to time divisio...

A Dichotomized Rendezvous Algorithm for Mesh Bluetooth Scatternets

A Bluetooth scatternet is formed by sharing some nodes (bridges) among piconets in a time division multiplex basis. Effective coordination of these bridge nodes is crucial for the smooth operation of a scatternet. In this paper, a distributed, two-phase RP scheduling algorithm called Dichotomized Rendezvous Point algorithm (DRP) is presented to address this problem. DRP makes the assumption tha...

An Efficient Scatternet Formation Algorithm for Dynamic Environments

There is increasing interest in wireless ad hoc networks built from portable devices equipped with short-range wireless network interfaces such as Bluetooth. This paper addresses issues related to internetworking such networks to form larger “scatternets.” Within the constraints imposed by the emerging standard Bluetooth link layer and MAC protocol, we describe an efficient online scatternet to...
