Performance Analysis of Wireless Network Modes in Conformance with IEEE 802.11b and WDS

Abstract:

Usage of wireless networks is rising in popularity. In this setting different kinds of networks for indoor environments, such as Ad-Hoc, IEEE 802.11b (Wi-Fi) and Wireless Distribution System (WDS) has been developed. In this paper, an analysis of Quality of Service (QoS) has been made for each network in order to verify the values of bit rate, delay, jitter and packet loss. For performance comparison of these networks, injection of UDP traffic was accomplished by means of the Distributed Internet Traffic Generator (D-ITG). Distance and number of obstacles were varied in several deployed network scenarios. In each scenario, QoS parameters were measured and efficiency was estimated. According to results, WDS networks have better performance which has 30% more efficiency in long distance communication than Ad-Hoc and 802.11 networks.
