Abstract :
IEEES02.11 wireless networks have become one of the most widely used. Due to open nature of wireless medium, information transmitted over the wireless channel is vulnerable to security attacks. Thus security in wireless network is a big challenge. 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 and response time in roaming scenario for IEEES02.11n WLAN standard. From the obtained numerical values, it is found that the security performance of transmission power slightly changes on varying the transmit power from high 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 decreased by 2-5% & 16-22% and response time is increased by 2-6% & 21-27% with packet size respectively.
