Read:
A Comparison of Mechanisms for Improving TCP Performance over Wireless Links.
Hari Balakrishnan, Venkat Padmanabhan, Srinivasan Seshan, and Randy H. Katz.
IEEE/ACM Transactions on Networking, December 1997.
Better still, read Hari's thesis -- it won the best doctoral dissertation
award a couple of years back.
If you are talking about adhoc networks i.e. bluetooth -- then bluetooth
itself is reliable, thats what L2CAP layer does --- is that a real world
system now ?
