Analyzing Load and Delay in Wireless LAN using TTL and Fragmentation

A wireless LAN or WLAN (wireless local area network) is one in which a mobile user can connect to a local area network (LAN) through a wireless (radio) connection. WLAN is standardized as 802.11 by IEEE. The services like FTP, HTTP demands a good flow in a network. So users expect a good network quality and a delay free environment. The size of the packets is a very important performance factor. Too small packets yield poor efficiency; too large packets are likely to get dropped and cause delay. In this paper, we analyze two parameters, Delay and Load in wireless LAN using TTL and fragmentation. OPNET has been used to evaluate the various simulation results.
