The subject of this thesis is to study and compare two heuristic algorithms for smart radio resource allocation, over an LTE system which provides 5MHz bandwidth. Specifically, BALSO and TWEAK algorithms were tested on a range of experiments in order to determine their performance in the metrics of processing time, energy efficiency and use of resources, over a ''bad urban microcell'' environment. The space for the installation of the system was defined as a square 1000m2, in which the micro base stations are placed at fixed respective locations set in LTE mode, where mobile terminals are placed at random positions, different for each simulation. The positioning of the mobile terminals in the grid is done in such a way as to create a hotspot in the central area of the grid, in order to simulate higher or lower load conditions compared with the rest of the grid. Experimental measurements were made using a downlink LTE system simulator utilizing the stochastic propagation model WINNER II.
