Vertical 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 کاملSignal threshold adaptation for vertical handoff in heterogeneous wireless networks
The convergence of heterogeneous wireless access technologies has been envisioned to characterize the next generation wireless networks. In such converged systems, the seamless and efficient handoff between different access technologies (vertical handoff) is essential and remains a challenging problem. The heterogeneous co-existence of access technologies with largely different characteristics ...
متن کاملThe QoS-Ensured Vertical Handoff Decision in Heterogeneous Wireless Networks
The multi-criteria vertical handoff algorithm plays an important role in heterogeneous wireless networks. There are two drawbacks in the available multi-criteria vertical handoff algorithms. The conventional algorithms do not give the feasible method to determine attribute weight values, and do not also consider the dependency relationship among the decision attributes, which are not mutually i...
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 کاملA Simple and Robust Vertical Handoff Algorithm for Heterogeneous Wireless Mobile Networks
Wireless networking is becoming an increasingly important and popular way of providing global information access to users on the move. One of the main challenges for seamless mobility is the availability of simple and robust vertical handoff algorithms, which allow a mobile node to roam among heterogeneous wireless networks. In this paper, motivated by the facts that vertical handoff procedure ...
