Transfer and Management of Broadband Traffic in Wireless Telecommunication Networks

The present thesis aims to study resource allocation techniques in fixed wireless networks in order to optimize their spectral efficiency as well as to investigate alternative broadband transfer methods. A brief overview of broadband wireless access networks with their characteristics is given and the fundamental resource management techniques proposed in the open technical literature are also referred. Then, a typical wireless broadband network model is presented and a comprehensive review of the key resource management techniques proposed in the literature is given. Following this, the proposed resource management techniques are presented and compared using proper simulation results. On the other hand, the analytical model of a wireless broadband traffic model over a terrestrial wireless optical link is analyzed. Its performance is extracted using analytical expressions of the average outage probability and the average error probability metrics. Appropriate simulation results are depicted as well. Furthermore, a network architecture comprising of several high amplitude platforms communicating with each other using optical links, is introduced in order to transfer broadband traffic over long distances. The outage probability performance is examined using either one-hop or multi-hop scenarios and suitable numerical results are provided. Finally, concluding remarks are summarized and suggestions for further research are indicated.
