Multi-Criteria Vertical Handover for Heterogonous Networks
In the next generation heterogeneous wireless networks, a user with a multi-interface terminal may have network access from different service providers using various technologies. Vertical Handover (VHO) is the capability to switch on-going connections from one Radio Access Network (RAN) to another. This switching is based on the discovered accesses, QoS constraints, operator policies, user pre...
متن کاملMulti-Criteria Vertical Handover Comparison between Wimax and Wifi
In next generation wireless networks, the most tempting feature is the ability of the user to move smoothly over different access networks regardless of the network access technology. In this paper we study the benefit of Multiple Attribute Decision Making (MADM) strategies for network selection. We compare three of these methods naming Simple Additive Weighting (SAW), Multiplicative Exponentia...
متن کاملMulti-criteria Vertical Handover Decision Algorithm in Heterogeneous Wireless Network
Vertical handover is essential to ensure service continuity in a heterogeneous network. Multi-criteria decision is proposed to reduce handover rate and optimizing usage of network resource compared to the conventional handover decision, which used single criteria. The algorithm is evaluated by assessing the performance in terms of number of handoff, load balance index, and network blocking prob...
متن کاملVertical Handover Management Employing Multi-criteria Decision Modeling in Heterogeneous Wireless Networks
enabling seamless connectivity in heterogeneous wireless networks and pervasive use of smartphones in daily life require high data speed and always best-connected services. The always best-connected services require fast and efficient vertical handover management. However, providing vertical handover management in heterogeneous wireless networks is a difficult task. Moreover, various issues are...
متن کاملSeamless Vertical Handover for 4G Wireless Networks
A user in 4G network needs to have a seamless vertical handover so as to backward compatible with 3G and 2G wireless networks. In the existing methods the handover is performed based on user policies at each time and by using the neural network model. This is an issue for the handover based on the time needed to take the handover and the reduction in traffic-carrying capacity. To overcome these...
