Improve TCP Performance in Ad Hoc Network by TCP-FSR
Zou Ling · Mini-micro Systems · 2005
Standard TCP misinterprets mobility loss in Ad hoc network as congestion loss,thus,it reduces the TCP performance for invoking congestion control action unnecessarily.Most current approaches use feedback from network or lower layer of intermediate nodes to improve TCP performance in Ad hoc network.However,current approaches may let TCP resumes transmission from an incorrect state when multiple link failures occur along a route at the same time,which make TCP invokes 'Fast Retransmit/Fast Recovery' in the period immediately following TCP resuming transmission.TCP-FSR proposed in this paper can solve this trouble.Analyses and simulations have proven the validity of TCP-FSR.
