Wireless networks have experienced immense growth in traffic loads over the last few years, putting yet greater strain on the capacity of wireless networks. A powerful approach to expand the capacity of networks is to deploy dense cellular networks so as to cover areas with high traffic density (hot spots), connected to a high-capacity fiber-optical backhaul network. A crucial challenge in such networks is to optimize the performance and minimize the energy usage in the presence of highly dynamic user populations with diverse traffic characteristics. Dynamic feeding of picocells by flexible routing of radio-over-fibre signals is foreseen as the enabling technology to address this challenge. In this thesis we study and develop algorithms do for three key decisions: 1) which users should be associated with which access points, 2) which frequencies and optical wavelengths to allocate to the various active access points, and 3) which access points to activate and which ones to power off. The developed algorithms have a strong self-organizing property, allowing them to dynamically react to changing traffic conditions without explicit prior knowledge of the traffic characteristics. Moreover, extensive simulations show that our algorithms are very effective in balancing the load among the different access points, and significantly increase the user-perceived throughput and delay.
