摘要

异构网络(HetNets)是指由不同类型的节点组成的通信网络,这些节点通过通信网络连接,部署了不同的无线接入技术,如 LTE、Wi-Fi、Zigbee 和 Z-wave,并使用不同的通信协议和工作频率。垂直切换是将移动设备从一种网络类型切换到另一种网络类型(如从蜂窝网络切换到 Wi-Fi 网络)的过程,是确保无缝用户体验和最佳网络性能的关键,而在切换过程中,切换触发估计是影响整体性能的关键步骤之一。本文对切换触发估计进行了数学分析。性能评估结果表明,使用基于速度、距离和不同移动性模型提出的切换触发条件,成功切换的概率有了显著提高。切换触发条件根据移动节点的速度、切换完成时间以及 HetNet 节点当前网络和目标网络的覆盖范围进行优化,并适当考虑了移动性模型。

Performance evaluation of handover triggering condition estimation using mobility models in heterogeneous mobile networks

Performance evaluation of handover triggering condition estimation using mobility models in heterogeneous mobile networks

Heterogeneous networks (HetNets) refer to the communication network, consisting of different types of nodes connected through communication networks deploying diverse radio access technologies like LTE, Wi-Fi, Zigbee, and Z-wave, and using different communication protocols and operating frequencies. Vertical handover, is the process of switching a mobile device from one network type to another, such as from a cellular network to a Wi-Fi network, and is critical for ensuring a seamless user experience and optimal network performance, within the handover process handover triggering estimation is one of the crucial step affecting the overall performance. A mathematical analysis is presented for the handover triggering estimation. The performance evaluation shows significant improvement in the probability of successful handover using the proposed handover triggering condition based on speed, distance, and different mobility models. The handover triggering condition is optimised based on the speed of the mobile node, handover completion time, and the coverage range of the current and the target networks of the HetNet node, with due consideration of the mobility model.
