Studies on Improvement and Application of TCP with Network Coding in Lossy NetworksNguyen Viet HaPrefaceThe proliferation of mobile devices with incre Studies on improvement and application of tcp with network coding in lossy networks ease of rich and diverse applications has led to an exponential growth of mobile data traffic while the request of consecutive connection becomes more and more demanded by users. Whereas, environmental data-lransmission is increasingly diverse and most of them arc lossy networks such as wireless lin Studies on improvement and application of tcp with network coding in lossy networks ks under severe environments (e.g., satellite network, long-distance fixed wireless backbone), wired links with legacy technologies (e.g.. Internet inStudies on improvement and application of tcp with network coding in lossy networks
developing regions) and links between mobile nodes (e.g.. Vchiclc-to-vehicle networks). In such networks, packet losses might be heavy and/or bursty Studies on Improvement and Application of TCP with Network Coding in Lossy NetworksNguyen Viet HaPrefaceThe proliferation of mobile devices with incre Studies on improvement and application of tcp with network coding in lossy networks rmation networking, the goal of this research is to realize packet-loss tolerant data transmission over lossy networks. The Transmission Control Protocol (TCP) is still dominantly used in many user applications but TCP performance is considerably degraded in lossy networks due to its loss-based cong Studies on improvement and application of tcp with network coding in lossy networks estion control. Thus. TCP with Network Coding (TCP/NC) has been proposed which can prevent the performance degradation by introducing packet loss recoStudies on improvement and application of tcp with network coding in lossy networks

TCP/NC and its variants proStudies on Improvement and Application of TCP with Network Coding in Lossy NetworksNguyen Viet HaPrefaceThe proliferation of mobile devices with incre Studies on improvement and application of tcp with network coding in lossy networks C-relatcd parameters arc not well adapted to diverse of loss conditions. We have seen the potential of TCP/NC as well as many problems which should be improved to increase the performance of data transfer. Therefore, this dissertationmainly focuses on improving the performance of TCP/NC to work well Studies on improvement and application of tcp with network coding in lossy networks in most conditions of lossy networks (random loss and burst loss) and adapt rapidly with lime-varying loss conditions.Three main contributions arc prStudies on improvement and application of tcp with network coding in lossy networks

The first one is a new effective retransmission mechanism for TCP/NC which can shorten the retransmission lime in heavy Studies on Improvement and Application of TCP with Network Coding in Lossy NetworksNguyen Viet HaPrefaceThe proliferation of mobile devices with incre Studies on improvement and application of tcp with network coding in lossy networks transmission mechanism can also encode all retransmitted packets to reduce the repealed losses: hence TCP timeout cases are limited and performance is increased. The second one is a method to estimate and adapt the NC-related parameters automatically, promptly and effectively based on observations o Studies on improvement and application of tcp with network coding in lossy networks f loss rale and loss burstincss conditions and a mathematical model of packet losses. This proposal can help TCP/NC work well in the complicated lossStudies on improvement and application of tcp with network coding in lossy networks

TCP/NC tunnel is proposed as an applicaStudies on Improvement and Application of TCP with Network Coding in Lossy NetworksNguyen Viet HaPrefaceThe proliferation of mobile devices with incre Studies on improvement and application of tcp with network coding in lossy networks nt memory or power. In addition. TCP/NC across loss-free but thin networks may waste scarce link bandwidth due to the redundant combination packets sacrificed for the lossy networks. TCP/NC tunnel is an appropriate solution for such networks.All proposals arc implemented and evaluated in Network Sim Studies on improvement and application of tcp with network coding in lossy networks ulator 3 which is a discreteevent network simulator for Internet systems, rhe results have shown that our approaches overcome the deficiencies of theStudies on improvement and application of tcp with network coding in lossy networks
