Performance Analysis of Secure Wireless Local Area Network Using Test-Bed

IEEE802.11 wireless networks have become one of the most widely used networks as users can connect and access the required information anytime and anywhere. Due to open nature of wireless medium, there are many security issues associated with them. In the present work an experimental analysis to study the impact of transmission power of access point on the performance of secure wireless network is analyzed in terms of throughput in roaming scenarios for IEEE802.11n WLAN standard. Three power levels high, medium and low have been considered for access point. Analysis has been done in terms of network through put. From the obtained numerical values, it is found that the security performance of transmission power IEEE802.11 LAN slightly changes on varying the transmit power from high level to medium level for both UDP and TCP traffic but on varying the power from medium to low level, the network throughput performance for UDP and TCP traffic is increased by 3% and 10% respectively.
