why traditional TCP fail in mobile networks?

Answer 1

TCP should not fail just because you are using a wireless network or a mobile computer. Something is wrong with your configuration. The problems are too varied to discuss them all here, but Wireless is a solid venue for computers and very reliable if configured properly. TCP/IP is the most common and wide spead protocol for the Internet and not subject to change and time soon, in fact, IPv6 is coming out more and more, and while it is still in its infancy, it will soon replace IPv4. Check your configuration, and if you do not have the proper experiance, have somebody you know who is do it, or have a technician come in.

I have been using wireless for two years and it is solid as can be, as are the wireless networks of those I know. We even stream multimedia throughout our networks without any bandwidth or connectivity problems.

Good luck and have a great day.

Unlike wired links, wireless network bandwidth is highly limited and the channel usually suffers from frequent and bursty loss due to its vulnerability to various kinds of interference. At the same time, the traditional TCP with its congestion control is well known for its poor performance over wireless links. This paper proposes a new protocol that (1) replaces TCP/IP over the wireless link by a simpler protocol with smaller headers, if the link is the last hop along a data path, (2) shifts functions needed to communicate with an Internet host using TCP/IP from the mobile host to the base station, so that the distinct wireless link is hidden from the outside Internet, and (3) exploits link-layer acknowledgments and retransmissions to quickly recover losses over the wireless link. Our simulation results show a substantial performance improvement achieved by the new protocol
