Abstract

Bluetooth is an emerging technology in wireless applications,and many related issues are yet to be explored bothin academia and industry. Because of the complexity andthe dynamics of computer networks, a good simulation toolplays an important role in the development stage. Of the existingsimulation tools, ns is a popular, open-source packagethat has a substantial support for simulation of TCP,routing, and multicast protocols over wired and wirelessnetworks. It also has BlueHoc as its extension for Bluetooth.Although BlueHoc offers many simulation functionsfor Bluetooth, all simulations must be done in a virtuallyfixed topology. Hence simulation about dynamic topologyconstruction-the first and an important step in establishinga Bluetooth network-cannot be conducted. Besides,BlueHoc offers only a limited support for building a network.It also lacks flexibility in device control, in animatedpresentation, and in modeling mobility. The main contributionof the paper is therefore to enhance BlueHoc to supportthe aforementioned functions.
