Dual Queue with Optimal Queue Selection to Enhance Tcp Fairness over Wireless Networks

The performance of TCP in the presence of handoff is effectively enhanced by the two schemes discussed in chapter 5. The EPRN scheme executes immediate recovery of lost packets during handoff and maintains the throughput of protocol by keeping the congestion control parameters unaltered. It also classifies the packet loss using a simple heuristic and by measuring the end-to-end delay encountered by the packet during transmission from the source to destination. The ETCP-VHO effectively handles both UVHO and DVHO by addressing the problem of packet reordering and premature timeouts. The schemes discussed in the previous chapters aimed to improve the throughput of TCP over wireless networks. In an asymmetric wireless network, fairness is one of the challenging issues in TCP flows.
