The evolution of hand-held devices and portable machines started the increase in demand for reliable, secure, and faster means of communication from wireless LAN infrastructures. This has lead to an enormous increase in the size of networks, which in turn has increased the cost and power consumption of access points and switches in the network infrastructure. While managing demand, networks become underutilized with less traffic demands and over utilized with more traffic demands. This research tends to discuss the best designs for maximum efficiency in terms of power and cost while retaining the best user experience. Designs were mainly evaluated based on the benefits of a centralized structure and a non-centralized structure. Furthermore, in order to understand the differences and make centralized structure more efficient in terms of power and cost, a new algorithm was designed with convex hull approach and was also implemented in the emulator kind of network testbed generating outstanding results and evaluations. The algorithm proposed in this thesis and the resulting design, if implemented in the future, could mean 60 percent additional savings in power consumption and costs.
