Optimization of Assigned Power and Bandwidth in Macro-Femto Cellular System Using Geometric Programming

Femtocells are used to increase indoor coverage and network capacity of traditional macro base stations (BS) deployments. Interference is key performance limiting factor in such heterogeneous mobile networks. In order to minimize the interference between macro- and femto base stations, the authors use a constrained optimization technique to optimally allocate bandwidth and power to macrocell and femtocell user equilibrium's (UEs). Matlab's Convex Programming (CVX) library is used to solve the optimization problem. Depending on the UEs' position from their serving base station (macro or femto) and their demand for higher data rates than minimum requirement data rate, the optimal power and bandwidth is assigned to each base station.
