Wireless networks are increasingly being implemented and its acceptance in the society is booming. In this paper, the performance analysis of 802.11 networks was done for different standards like IEEE 802.11a, 802.11b, and 802.11g in different scenarios. The throughput and traffic dropped for such networks in homogeneous and heterogeneous groupings were studied. Also Bluetooth nodes were tested with 802.11b nodes and the network performance was analyzed. Observations on performance were eventually done based on these network simulations that were implemented using existing network models.
