Coverage and Analysis of Obstructed Indoor WLAN using Simulation Software and Optimization Technique

WLAN is a flexible data communication system implemented as an extension to or as an alternative for, a wired LAN. This paper presents the placement of access points (AP) as a nonlinear optimization problem. The work explores the measured data in terms of signal strength in the indoor WLAN 802.11g at Malviya Bhavan, Boys Hostel Building, Indian Institute of Technology, Roorkee, Saharanpur Campu...

A Novel UWB-based Multilateration Technique for Indoor Localisation

In this paper, we present a novel geometrically driven multilateration technique that is based on Ultra-Wideband (UWB) technology. We refer to our proposed solution as Time Reflection of Arrival (TROA). We demonstrate in this paper that the position estimation error is improved upon by carefully considering the inherent properties of the UWB technology and the reflection properties of transmitt...

Spearman’s Rank Order Correlation Coefficient

• In this lesson, we will learn how to measure the coefficient of correlation for two sets of ranking. • The coefficient of correlation, r, measures the strength of association or correlation between two sets of data that can be measured. Sometimes, the data is not measurable but can only be ordered, as in ranking. • For example, two students can be asked to rank toast, cereals, and dim sum in ...

The Kendall Rank Correlation Coefficient

The Kendall (1955) rank correlation coefficient evaluates the degree of similarity between two sets of ranks given to a same set of objects. This coefficient depends upon the number of inversions of pairs of objects which would be needed to transform one rank order into the other. In order to do so, each rank order is represented by the set of all pairs of objects (e.g., [a,b] and [b,a] are the...
