Performance evaluation of WLAN IEEE802.11n using riverbed modeler

A Wireless Local Area Network otherwise as WLAN gives a flexible data communication system rather than using a wired LAN within a building. It uses radio frequency to transmit and receive data which minimizes the need for wired connections. The intention of this paper is to evaluate the performance of WLAN protocol network IEEE802.11n with the data rate of 2.4GHz which is achieved by using optimized network simulating tool, RIVERBED modeler 17.5. The performance of the protocol were measured by setting up three main functions. Media access Delay, data packet loss, Data dropped buffer overflow. Data packet received by all the workstation is larger than the other protocols. The possibility of data flow and communication will be higher. In addition, the delay that occurs can be eliminated by increasing the channel transmission rate
