目的——过去几年出现了几种新的网络类型。许多这些网络正在连接在一起，为移动用户提供始终连接到互联网的能力，这需要从一个网络无缝过渡到另一个网络，而不会对正在进行的连接造成中断。为了在切换期间保持连接，需要知道移动站可访问的所有网络。本文旨在提出一种新颖的节能网络发现方法，能够快速发现和选择可用的接入网络。设计/方法/途径——评估所提出的方法在由异构网络（例如无线局域网、蜂窝网络）组成的实际网络测试台上的性能。研究结果——发现该方法比其他网络发现方法的电池功耗提高了 12.4% 至 19.1% 原创性/价值——本文提出并实施了一种新颖的......
Purpose – Several new network types have emerged over the last couple of years. Many of these networks are being connected together to provide mobile users with the capability of staying always connected to the Internet which requires seamless transitions from one network to another without causing interruption to on‐going connections. To maintain connectivity during handoff, all the networks that are accessible to the mobile station need to be known. The paper aims to propose a novel energy‐efficient network discovery approach that enables fast discovery and selection of available access networks.Design/methodology/approach – The performance of the proposed approach over an actual network testbed consisting of heterogeneous networks (such as wireless local area, cellular) is evaluated.Findings – It was found that the approach yields between 12.4 and 19.1 per cent improvement in battery power consumption over other network discovery approaches.Originality/value – The paper proposes and implements a novel ...
