摘要/Abstract

摘要：

针对异构无线网络环境中如何动态选网的问题,提出了一种基于上下文感知的网络选择切换策略。该策略提出一个动态的网络感知解决方案,引入模糊逻辑切换判决,以某项选择指标为依据过滤掉不满足需求的接入网络,并设计一种网络得分函数对网络进行排名计算。仿真实验表明,所提的切换策略可以为用户选择适合的接入网络，实验资源的有效利用。

Abstract:

In view of the problem that how to select the network dynamically in heterogeneous wireless network environment, an network selection and handover strategy based on context-awareness was proposed. A dynamic network solution and a fuzzy logic handover decision were proposed. Based on them, the strategy chose a selection index to filter those access networks that did not satisfied the requirements and designed a network score function for network ranking calculation. The simulation results show that the proposed handover strategy can select a suitable access network, and effectively use the resources.
