An Optimization Framework for Two-tier Cellular Network Resource Allocation and Handover

The Orthogonal Frequency Division Multiplexing Access (OFDMA) andmacro-femto two-tier heterogrneous network are the core technologies usedin 4G and 5G cellular networks. These pose new challanges and optimizationpotential for network resource allocation with consideration of fairness as wellas for user equiptment (UE) handoff with consideration of resource allocation.This thesis studies both problems, and analyses the inherent difficulties inthe problem domain. Then several optimization algorithms are proposed tosolve the problem. An optimization framework is proposed to integrate thealgorithms together
