异构网络中基于终端决策的通用垂直切换算法

摘要

Vertical handoff is a key technology in heterogeneous network, but the current algorithms mainly focus on specific networks or handoff procedure. This paper presents a network-independent algorithm, the simulation results prove that the new algorithm performs better than traditional algorithms in supporting multiple tasks and utilizing energy effectively.%垂直切换是异构网络中的关键技术,目前已有的垂直切换算法大多是针对特定的网络或切换过程的某个环节,提出一种与网络类型无关的通用垂直切换算法,仿真结果表明该算法在支持多任务,有效利用能量方面比传统方法有很大的改进.
