Dwell Time Prediction Model for Minimizing Unnecessary Handovers in Heterogenous Wireless Networks, Considering Amoebic Shaped Coverage Region
摘要：
多年来，垂直切换必要性估计吸引了众多研究人员的兴趣。尽管集成不同的无线平台的吸引人的好处，移动用户面临着有害的切换的问题。本文使用了广泛的几何和概率分析建模的WLAN小区的覆盖区域。因此，提出了一个现实的和新颖的模型，试图最大限度地减少不必要的切换和切换失败的移动节点（MN）穿越WLAN小区从第三代（3G）网络。估计停留时间以及阈值，以确保MN的最佳切换决策，同时将不必要的切换和切换失败的概率保持在可容忍的范围内。Monte-Carlo模拟进行了显示所提出的模型的行为。通过比较该模型与现有模型的不必要的切换最小化的结果进行了验证。
英文摘要：
Over the years, vertical handover necessity estimation has attracted the interest of numerous researchers. Despite the attractive benefits of integrating different wireless platforms, mobile users are confronted with the issue of detrimental handover. This paper used extensive geometric and probability analysis in modelling the coverage area of a WLAN cell. Thus, presents a realistic and novel model with an attempt to minimize unnecessary handover and handover failure of a mobile node (MN) traversing the WLAN cell from a third generation (3G) network. The dwell time is estimated along with the threshold values to ensure an optimal handover decision by the MN, while the probability of unnecessary handover and handover failure are kept within tolerable bounds. Monte-Carlo simulations were carried out to show the behavior of the proposed model. Results were validated by comparing this model with existing models for unnecessary handover minimization.
