Abstract: Due to the fast development of technology, future communication and transmission are totally dependable on wireless network. Wireless networks are generally less efficient and irregular compared to wired networks, which makes the quality of service (QoS) provision a larger challenge for wireless communications. This paper presents a comparison between IEEE 802.11b & 802.11g network in terms of quality of service using the Opnet simulation program and the quality of service provided by the network itself can be described by different parameters called QoS parameter such as Delay, retransmission count, download response time and data drop.

Keywords: IEEE 80211b, g, delay, packet loss and opent
