Design and Implementation of Decisioning System for Wifi Access Point Installation using Genetic Algorithm

This paper presents the design and implementation of a WiFi indoor localization system using genetic algorithm. The coverage capability of the wireless access point is an important parameter in the design to estimate the distance from the transmitted and received signals. The main purpose of this work is to find the effective number of wireless access points in the design area by using genetic algorithm. The Received Signal Strength (RSSI) is measured for the signal quality. The test area consists of the multiple classrooms on the same floor inside the building and the conditions are unobstructed and used the line-of-sight for transmitted and received signals. The experimental results by measuring the received signal through a laptop are indicated that RSSI = -35 dBm at a distance of 5 meters is a prominent indicator of signal quality that can be used to search a variety of information from internet inside the classroom.
