Analytic Performability Model of Vertical Handoff in Wireless Networks
Problem statement: The next generation wireless systems should be designed to support heterogeneous traffic with seamless mobility. A single network alone cannot cope up with such heterogeneous requirements. Hence it is desirable to interoperate between diverse and complementary Radio Access Technologies (RATs). In such system, user will switch between different Radio Access Technologies (RATs)...
متن کاملVertical Handoff in Wireless 4G Heterogeneous Networks
In today’s high-speed communication era, when a user moves from one network to another, voice call and video streaming should not be interrupted. Different wireless network technologies such as WLAN, a cellular network, WiMAX coexist and they have different data rate and different area of coverage. Therefore, it is very challengeable to design an efficient vertical handoff scheme which will sat...
متن کاملVertical Handoff in Wireless Overlapping Networks
As wireless communications services continue increasing, continuous coverage and QoS parameters must be guaranteed to the end user. Due to the fact that in most places several wireless networks might be available, handing off between them can significantly enhance network efficiency and user satisfaction. In such a scenario, continuous environment monitoring is required for estimating links’ co...
متن کاملSurvey of Vertical Handoff Models in Heterogeneous Wireless Networks
B.G. Kim and Hengky Susanto Hwang S. Lee Computer Science Dept. Electrical Eng. Dept. Univ. of Mass. Lowell KAIST {kim, hsusanto}@cs.uml.edu [email protected] Abstract A vertical handoff technique switches a mobile station among wireless networks with different technologies. Since a different network may not support the same QoS, the vertical handoff technique has to consider user QoS...
متن کاملRequirements of Vertical Handoff Mechanism in 4G Wireless Networks
The importance of wireless communication is increasing day by day throughout the world due to cellular and broadband technologies. Everyone around the world would like to be connected seamlessly anytime anywhere through the best network. The 4G wireless system must have the capability to provide high data transfer rates, quality of services and seamless mobility. In 4G, there are a large variet...
