Battery-Bandwidth Based Handover Framework for 3G/WLAN Using Android Handheld Devices
نویسندگان
چکیده
In a heterogeneous network environment, transparent horizontal and vertical handover is a much desired feature. Effective handover solution would allow mobile device users to stay steadily connected, seamlessly switching between different access networks. If it is consistently connected to networks which offers best Quality of Service (QoS) then that would dramatically improve user experience. Switching of network requires more device energy and also high bandwidth to guarantee the QoS. Automatic handover between 3G and WLAN networks is typically done when the current network link is going down. Current devices does not consider these two major metrics during handover. Hence, we propose a framework for creating our own custom handover solutions which could run on the clients’ Android based mobile devices. To provide an example of using the framework, we implement and test our proposed framework in Android based hand held devices and showcase the improvement in QoS. Keywords-: 3G, Android, battery, handover, remaining energy, seamless switching, WLAN

متن کاملA Lightweight Macro-mobility Framework
This paper presents the design of a lightweight framework to provide vertical handover for macro-mobility on handheld devices. The framework is designed for mobile-controlled handover and does not require modification of the Internet infrastructure. The framework enables users to control the entire vertical handover process so handover decisions are driven by user preferences rather then ISP co...
متن کاملA new architecture for 3G and WLAN integration and inter-system handover management
WLAN has strong potential to provide a perfect broadband complement to the 3G wireless systems. This has raised much interest in their integration. In this paper, a novel architecture using the Network Inter-operating Agent (NIA), and Integration Gateway (IG) is proposed to integrate the 3G systems and WLANs of various providers that may not necessarily have direct service level agreement (SLA)...
