Resum\u00e9 :<\/strong><\/p>\n

The popularity of the great variety of Internet usage brings about a significant
\ngrowth of the data traffic in telecommunication networks. Data transmission ef-
\nciency will be challenged under the premise of current network capacity and
\ndata fl ow control mechanisms. In addition to increasing financial investment to
\nexpand the network capacity, improving the existing techniques is more ratio-
\nnal and economical.<\/p>\n

Various cutting-edge researches to cope with future network
\nrequirements have emerged, and one of them is network coding. As a nat-
\nural extension in coding theory, it allows mixing different network fl ows in the
\nintermediate nodes, which changes the way of avoiding collisions of data
\nflows. It is claimed to be a sharp tool which helps achieve better throughput and reliabil-
\nity, security, and robustness in various network environments and applications.<\/p>\n

This dissertation focuses on the use of network coding for multicast in fixed mesh
\nnetworks and distributed storage systems. We first model various multicast rout-
\ning strategies within an optimization framework, including tree-based multicast
\nand network coding; we solve the models with efficient algorithms, and compare
\nthe coding advantage, in terms of throughput gain, in medium size randomly
\ngenerated graphs. Based on the numerical analysis obtained from previous ex-
\nperiments, we propose a revised multicast routing framework, called strategic
\nnetwork coding, which combines standard multicast forwarding and network cod-
\ning features in order to obtain the most benefit from network coding at lowest cost
\nwhere such costs depend both on the number of nodes performing coding and the
\nvolume of traffic that is coded.<\/p>\n

Finally, we investigate a revised transportation problem which is capable of calculating a static routing scheme between servers
\nand clients in distributed storage systems where we apply coding to support the
\nstorage of contents. We extend the application to a general optimization problem,
\nnamed transportation problem with degree constraints, which is widely used
\nin different industrial fields, including telecommunications, but has not been stud-
\nied very often. For this problem, we derive some preliminary theoretical results
\nand propose a reasonable Lagrangian decomposition approach.<\/p>\n
