To develop a solution for load-proportional energy usage during wireless network access, this thesis considers networking hardware with support for dynamic frequency scaling (DFS). The proposed system is based on changing the operating clock frequency of the network interface cards as a function of the offered load, in order to reduce to energy consumption. The first contribution of the thesis is the design of a frequency selection mechanism that tries to minimize the energy consumption. The second contribution of the paper is the design of a pipelined architecture for the implementation of DFS that reduces the delays associated with the use of DFS. The third contribution of the thesis is the development of a queuing model to evaluate the energy-delay tradeoff associated with use of DFS on wireless network interface cards. Finally, the last contribution of this thesis is the development and analysis of a threshold based sleep scheduling mechanism for energy savings in a wireless network.
