Handover in Bluetooth Networks using Signal Parameters

Fazli Subhan, Halabi Hasbullah, Azat Rozyyev and Sheikh Tahir Bakhsh

Bluetooth is an established standard for low cost, low power, wireless personal area network. Currently Bluetooth does not support any handover protocol in which handoff occurs dynamically, when a Bluetooth device is moving out of the piconet. This paper presents Bluetooth handover concept in terms of measuring the signal parameters with respect to localization. These parameters are Received Signal Strength Indicator (RSSI), Link Quality (LQ), Transmitted Power Link (TPL) and Received Power (RX). According to the experimental analysis based on Bluetooth specifications, only Received Power RX is best suited for distance estimation and handover decision. Furthermore this paper discusses location estimation techniques, Bluetooth signal parameters for distance estimation and finally experimental analysis of signal parameters and their comparisons with distance is discussed. The main objective of this paper is to analyze the relation between Signal parameters and Handover. The parameter selected for distance based measurement can be used as threshold value for handover initiation. All the work is being done in BlueZ using Linux kernel 2.6.

Merci pour ces auteurs de leur apports dans le monde de la recherche. En effet j'ai aimer leurs travaux et j'aimerai moi aussi faire un travail presque similaire dans le cadre du Wifi. c'est pour cette raison que je demande de l'aide aux chercheurs de aiguillé dans ce veux d'abord savoir si cette même paramètre peut-être considéré comme paramètre pour déclencher le handover pour une application de téléphonie mobile? sinon quel est le meilleur paramètre.
Ensuite quel est la valeur seuil(distance) maximale dans une cellule(zone de couverture d'un AP émettant au plus à 300m) qui offre une communication acceptable pour la téléphonie mobile.

Thank you for these authors for their contributions in the research world. In fact I love their work and would like me too do work almost similar in the Wifi. this is why I asked for help researchers in this referral first want to know if the same parameter can be considered as a parameter to trigger the handover for a mobile phone application? otherwise what is the best setting.
Then what is the threshold value (distance) up in a cell (coverage area of ??an AP emitting at 300 m) which offers an acceptable communication for mobile phones.
