Due to the rapid developments in the area of wireless communication and the popularity of the Internet packet data services for applications like e-mail, file transfer like ftp, web surfing like http, interactive remote terminal applications like telnet, mobile computing etc., over wireless are gaining importance. Most of these applications make use of reliable end-to-end transport protocol such as TCP. TCP has self-generating error and flow control schemes. It performs well in wired networks, where packet losses are primarily due to congestion. Packet loss in wireless networks could be due to bit error rate (BER) or disconnections due to mobility.
