4G网络中基于遗传算法的垂直切换决策
Vertical Handoff Decision Based On Genetic Algorithm in 4G Network
摘要：
移动时代的快速发展是为了支持尽可能多的移动设备，使用户能够随时随地在常见的实际应用方面受益，例如互联网访问，视频点播，视频会议系统和更多的应用。在本文中，在无线通信中的移动世代的审查，以突出和比较的问题和挑战，涉及到每一代从早期的几代开始，沿以下几代，最后到第四代（4G）。4G无线网络旨在补充和取代当前几代。随时随地传输信息，无缝连接各种信息和服务，接收大量信息、数据、图片、视频等，是4G的关键特征。根据移动通信的发展趋势，4G将具有更宽的带宽、更高的数据率、更平滑和更快的切换，以提供跨多种无线系统和网络的无缝服务。无缝移动性的主要问题之一是切换管理。设计智能切换管理方案是4G系统面临的主要挑战。本文提出了一种基于遗传算法的自适应多属性垂直切换判决算法。
英文摘要：
The rapid improvement of the mobile generations was for the purpose of supporting as many mobile devices as possible that could benefit the users at anytime and anywhere in terms of common practical applications such as internet access, video-on-demand, video conferencing system and many more applications. In this paper, a review for the mobile generations in the wireless communications is pre-sented in order to highlight and compare the issues and challenges that are involved in each generation starting from the earlier generations along to the following generations and finally till the 4th Generation (4G). The 4G wireless network is intended to complement and replace the current generations. Accessing information anywhere, anytime, with a seamless connection to a wide range of information and services, and receiving a large volume of information, data, pictures, video, and so on, are the keys features of 4G. Based on the developing trends of mobile communication, 4G will have broader bandwidth, higher data rate, and smoother and quicker handoff to provide seamless service across a multitude of wireless systems and networks. One of the major issues of seamless mobility is handoff management. It is a major challenge to design intelligent handoff management schemes for 4G-systems. In this paper we have presented the design of an adaptive multi-attribute vertical handoff decision algorithm based on genetic algorithm which is both cost effective and useful.
