Vertical Handover Decision Strategies in Heterogeneous Wireless Networks
The next generation wireless networks comprises of mobile users moving between heterogeneous networks, using terminals with multiple access interfaces and services. The most important issue in such environment is ABC (Always Best Connected) i.e. allowing the best connectivity to applications anywhere at any time. For always best connectivity requirement various vertical handover strategies for ...
متن کاملAn Intelligent Vertical Handover Decision Algorithm for Wireless Heterogeneous Networks
The Next Generation Wireless Networks (NGWN) should be compatible with other communication technologies to offer the best connectivity to the mobile terminal which can access any IP based services at any time from any network without the knowledge of its user. It requires an intelligent vertical handover decision making algorithm to migrate between technologies that enable seamless mobility, al...
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 کاملContext-Aware Decision Model for Vertical Handover in Heterogeneous Networks
Present day mobile networks are evolving towards heterogeneous overlaying infrastructure. Traditional handover decisions that are mainly based on signal strength are not sufficient to provide ubiquitous and seamless mobility across heterogeneous networks. Intelligent handover decision is needed so that users can select the best option available from diverse networks and services as per their re...
متن کاملSecure and Efficient Vertical Handover in Heterogeneous Wireless Networks
-------------------------------------------------------------------ABSTRACT-------------------------------------------------------------Handover occurs when a wireless node switches from one network to another. One of the main requirements of this process is to make it secure by using reliable security mechanisms, but it can decrease performance as well. So it is very essential to maintain bala...
