Abstract: This paper proposes a mobility-aware handover scheme for millimeter-Wave (mmWave) heterogeneous networks (HetNets) based on a Cartesian-plane approach (CPH). The scheme leverages the unique characteristics of mmWave propagation, spatial distribution, mobility pattern of User equipment (UE) and the available bandwidth in each cell to select the most suitable cell to achieve seamless handover and enhance network performance. The CPH scheme utilizes a Cartesian coordinate system for UE position estimation and prediction. This approach allows for efficient calculation of the distance between UEs and available base stations (BSs), enabling rapid handover decision making. It also incorporates the concepts of obstacle-free and obstacle-based coefficients in relation to Line-of-Sight (LoS) and Non-Line-of-Sight (NLoS) communication links. The technique is evaluated through simulations, demonstrating its effectiveness in improving handover success rate, and enhancing network throughput compared to the standard Rate-based handover (RBH) and the Seamless Handover Technique (SMART) handover models using number of handovers and average throughput as performance metrics. Simulation results obtained showed that the proposed scheme in terms of number of Femto Base Station (FBS) achieved 53.98% and 6.87% handover percentage reduction and 9.39% and 9.15% average throughput percentage improvement respectively when compared to the existing handover models.
