The majority of services that deliver personalized content in smart buildings require accurate localization of their clients. This article presents an analysis of the localization accuracy using Bluetooth Low Energy (BLE) beacons. The aim is to present an approach to create accurate Indoor Positioning Systems (IPS) using algorithms that can be implemented in real time on platforms with low computing power. Parameters on which the localization accuracy mostly depends are analyzed: localization algorithm, beacons’ density, deployment strategy, and noise in the BLE channels. An adaptive algorithm for pre-processing the signals from the beacons is proposed, which aims to reduce noise in beacon’s data and to capture visitor’s dynamics. The accuracy of five range-based localization algorithms in different use case scenarios is analyzed. Three of these algorithms are specially designed to be less sensitive to noise in radio channels and require little computing power. Experiments conducted in a simulated and real environment show that using proposed algorithms the localization accuracy less than 1 m can be obtained.

ABSTRACTThis article analyses how the state in Senegal has managed the hajj since the liberalisation era in the early 2000s. Although the essence of the hajj is religious, it is also deeply political and requires that the state manages complex relations with pilgrims, religious leaders, private travel agencies, politicians and Saudi authorities. This article argues that three inter-related imperatives structure the conduct of the Senegalese state: a security imperative, a legitimation imperative, and a clientelistic imperative. Security concerns lead the state to monitor and control pilgrims travelling to Mecca. Legitimation is seen in the collaborative relations with Sûfi orders and in the framing of the hajj organisation as a ‘public service’. Finally, given the magnitude of financial and symbolic resources attached to the hajj, clientelistic relations are constitutive of state officials’ actions. Overall, despite the post-2000 liberalisation of the hajj, the state has maintained its role as a gatekeeper, regulator and supervisor.
