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

Handover in the Wild: The feasibility of vertical handover in commodity smartphones
2013 IEEE International Conference on Communications (ICC), 2013Today commodity mobile devices are frequently equipped with two wireless access technologies, WiFi and 3G/4G. To enable continuous connectivity it is vital that these terminals provide for vertical handover between different technologies. Particularly, they should provide a vertical handover that complies with the timeliness requirements of soft real ...

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.

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 ...

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

Security context transfer in vertical handover
14th IEEE Proceedings on Personal, Indoor and Mobile Radio Communications, 2003. PIMRC 2003., 2004This paper presents solutions for security context transfer for vertical handover between heterogeneous networks. Seamless vertical handover is an important function of Beyond 3G systems. Context transfer can help support seamless vertical handover while maintaining required security level. So as to come to solutions for security context transfer, this
