In this thesis, some analytical frameworks have been developed to analyze the effect of different system parameters on handover performances in heterogeneous network (HetNet) and based on such frameworks, some efficient handover algorithms have been proposed. The study starts with an analytical framework to investigate the effect of resource allocation mechanisms, upper layer mobility management protocols (MMPs) and handover decision metrics on user perceived throughput. This analysis reveals that among other factors, handover decision metric plays a crucial role in determining user perceived throughput in HetNet. Subsequently, we develop two handover decision metrics for ultra dense networks (UDN) and unlicensed band communications specifically. For UDN scenario, a handover mechanism has been developed to deal with the period of time prior to handover initiation when a mobile terminal (MT) is connected to the serving cell but not getting the requested data rate. In unlicensed band communication, channel conditions may fluctuate drastically due to the interference caused by the co-existence of several networks in unlicensed band. For such a scenario, a handover mechanism has been proposed to select the optimal target network from a set of candidate networks. To provide seamless connectivity in HetNet, dual connectivity (DC) and separation between control and user planes have been emerged as promising solutions. An analytical framework has been developed to investigate the performance of DC in control-user plane split HetNet explicitly considering the data rate demands of the MTs, traffic arrival pattern and channel conditions. Finally, we analyze the handover performances of different classes of MMPs considering the effect of underlying handover execution mechanisms such as hard and semisoft. Based on this analysis, different combinations of MMPs and handover execution mechanisms have been prioritized using analytic hierarchy process. The significance of the developed analytical frameworks lie in the fact that these analyses would provide deeper insight towards service guarantee and system design in HetNet.
