Modeling and simulation of ieee 802.11 wireless-lan and bluetooth piconet range interference

Abstract

The proximity of wireless devices with one another often results in interference in the unlicensed 2.4 GHz ISM bandwidth. Interference has been recognized as a major problem to wireless network performance and improvement. In this paper we report a proposed and investigated Interference Range Model (IRM), a model that allows a user to determine the acceptable range of interference in a given environment. A Java environment for modeling, simulating, and analyzing acceptable/cutoff ranges of interference based on the IRM is discussed. The model was tested on ranges of interferences for Bluetooth devices in a piconet and IEEE 802.11 devices in the wireless LAN setup, which consequently provided a method for determining the signal-to-interference ratio (SIR) for the two protocols. With this approach, it is expected that a model for calculating and calibrating particular threshold values, or SIRs, and the corresponding ranges of interference can be determined for other wireless protocols
