Abstract : In highly dense LTE networks, with the increased number of users requesting services in a cell, blocking will occur for some users. To deal with this, techniques for increasing the capacity of the cell must be adopted. Creating extra small cells with low transmitting and receiving powers inside the macro cell will enable reusing the available frequency, and thus expanding the capacity of the network. However, because the nature of mobile users is dynamic and unpredictable, it would not be ideal to install infrastructure to create such small cells. Instead, some users inside the LTE cell will be promoted as Cluster-Heads (CHs) and act as relay stations for other users. In this kind of topology, specific allocation of users into different clusters is required and therefore clustering techniques can be adopted. In this thesis, a number of clustering techniques are implemented and compared. Clustering is based on creating small groups of users. The topology of each cluster consists of one Cluster-Head (CH) that communicates directly with the Base Station (BS), and a number of users, called slaves, that relay their communication through the CHs. Communications inside each cluster will only require low power. This will enable reusing the available frequency and increasing the number of connected users. Proper frequency allocation and power control are implemented in order to avoid excessive interference and achieve capacity enhancements.
