Proceedings of the 7th ACM workshop on Performance monitoring and measurement of heterogeneous wireless and wired networks, 2012
The increasing popularity of portable devices such as netbooks and smartphones, along with the wide deployment of wireless technologies such as Wi-Fi, WiMAX and UMTS, make users demand for continuous connectivity. This demand requires not only being attached to a network, but possibly to the best performing one, or at least to a network able to fulfill

A user-centric analysis of vertical handovers
Proceedings of the 2nd ACM international workshop on Wireless mobile applications and services on WLAN hotspots, 2004To implement seamless mobility inside an integrated, multiple (e.g. GPRS/WiFi) access system, a vertical handover policy has to be devised. This is usually done at the mobile terminal, allowing it to be customized from a end-user perspective, in order to fit individual needs/preferences.

Vertical Handover Decision in an Enhanced Media Independent Handover Framework
2008 IEEE Wireless Communications and Networking Conference, 2008Vertical handover decision making is one of key problems in heterogeneous network environment. In IEEE 802.21 standard, a Media Independent Handover (MIH) framework is presented to facilitate handover with measurements and triggers from link layers. However, vertical handover decision making can benefit from the information more than link layers.

On UDP continuity over vertical handovers
Computer Networks, 2013Today's mobile devices such as smart phones are equipped with multiple wireless access technologies, so multi-radio operation is becoming the norm. These devices frequently face vertical handover scenarios such as exiting Wi-Fi hotspot towards cellular network coverage.

Improvement of SCTP Performance in Vertical Handover
2008 Eighth International Conference on Intelligent Systems Design and Applications, 2008A heterogeneous wireless network integrating IEEE 802.11 WLAN and 3G/UMTS mobile phone system will be a common scenario in future mobile networking. The multi-homing feature of SCTP and the dynamic address configuration extension had made seamless vertical handover possible in heterogeneous mobile wireless networks. However, an ongoing SCTP association

A model to evaluate vertical handovers on JRRM
21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010In a heterogeneous cellular networks environment, users behaviour and network deployment configuration parameters have an impact on the overall Quality of Service. This paper proposes a new and simple model that, on the one hand, explores the users behaviour impact on the network by having mobility, multi-service usage and traffic generation profiles ...

Seamless Proactive Vertical Handover Algorithm
2011 Eighth International Conference on Information Technology: New Generations, 2011At present, none of the wireless access or mobile cellular network technologies provides ubiquitous coverage and the complete set of services required by the users. Therefore, the next generation of wireless networks i.e. 4th Generation (4G) network aims at the integration of these distinct yet complementary networks to satisfy user requirements and to

Vertical handover among broadcast networks
2009 6th International Symposium on Wireless Communication Systems, 2009In this article we propose strategies for optimization of vertical handover among broadcast networks. The specific technologies of DVB-H and UMTS/MBMS are taken into account for the modelling of technological parameters including energy consumption and frame loss.
