Proportionally distributed resource allocation in small-cell networks

Efficient resource allocation is one of the most challenging facet in small cell deployment. With continuous research, many algorithms have been developed in this regard. The proposed algorithm is for small cell downlink on a large scale with the context of orthogonal frequency division multiple access. The proposed algorithm has 4 stages, one of which also incorporates device-to-device (D2D) communication inside a small cell. The algorithm uses distributed resource allocation for downlink model based on user demand. A simulation environment is developed to study the quantitative effects of proposed algorithm. Poisson random distribution is used to model the user and access point locations. The interference analysis to determine maximum distance of D2D connection within a small cell is also provided. Performance comparisons between fixed resource allocation, partially distributed allocation and the proposed, proportional resource allocation algorithm with and without D2D are also shown. The simulations are carried out in MATLAB 2013.
