Transfer and Management of Broadband Traffic in Wireless Telecommunication Networks

Abstract. 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 tech-niques 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 mod-el over a terrestrial wireless optical link is analyzed. Its performance is extract-ed using analytical expressions of the average outage probability and the aver-age error probability metrics. Appropriate simulation results are depicted as well. Furthermore, a network architecture comprising of several high amplitud
