Measurement of Wireless Service Quality in Guest House of NIT Rourkela

Abstract

Wireless Local Area Networks (WLANS) have emerged as an untethered alternative for access networks. There is a strong and growing demand of WLANS in consumer markets and industrial markets such as health,education, airports etc. Currently our Institute is also planning for wireless connectivity in the campus area. By using Network Simulation Software such as Qualnet[1], the performance of wireless networks[3] in a scenario ( building or campus) can be studied. By loading the blueprint of the scenario (building or campus) propagation modeling techniques can now predict user data throughput based on radio signal strength In this paper we have performed detailed simulations of measurement of wireless
service quality in the Guest House of NIT Rourkela. The Autocad drawing of Guest House was studied and a realistic scenario was created in Qualnet placing the different nodes in various lacations. The throughput measurement using different number of access points and for different applications (FTP, Streaming Audio) is studied. The number of access
points were varied from 1 to 4 and the file size for FTP applications was also varied till a saturated value of throughput was obtained. By laying out the blueprint of the scenario in network modeling softwares such as Qualnet[1] wireless local area networks can be planned effectively and their performance can be studied exhaustively.
