In heterogeneous networks environment, Vertical Handover Decision (VHD) algorithms help mobile terminals to choose the best network between all the available networks. VHD algorithms provide the QoS to a wide range of applications anywhere at any time. In this paper, a generic and novel solution to solve the Vertical Handover (VHO) problem has been developed. This solution contains two major subsystems: The first subsystem is called elimination system. Elimination system is received the different VHO criteria such as received signal strength, network load balancing and mobile station speed from the different available networks. After that, the inappropriate alternatives are eliminated based on the elimination conditions. The second subsystem is a Multiple Criteria Decision Making (MCDM) system that chooses the appropriate alternative from the remaining alternatives of the elimination phase. For simulate the proposed solution, MATLAB program is used with aid of MATLAB-based toolbox that is called RUdimentary Network Emulator (RUNE). The combination of both subsystems avoids the processing delay caused by unnecessary computation over available networks which do not ensure connection performance. Also it avoids increasing the number of unnecessary handovers, ping pong effect, blocking rate and dropping rate by reducing the handover failure rate. A performance analysis is done and results are compared to other reference algorithms. These results demonstrate a significant improvement over other reference algorithms in terms of handover failure rate, percentage of satisfied users, and percentage of the low cost network usage.

For a satisfactory user experience, MTs must be able to seamlessly transfer to the best Radio Access Technologies (RATs) between all available candidates with no perceivable interruption to an ongoing conversation, which could be a voice or video session. Such ability to Hand-Over (HO) among Heterogeneous Wireless Networks (HWNs) is referred to as Vertical Handover (VHO). VHO algorithms are one significant challenge for Radio Resource Management (RRM) in HWN. The VHO is one of the key components that must be addressed and considered carefully in the HWN environments and need to be designed to provide the required Quality of Service (QoS) to a wide range of applicationsThe performance of the VHD algorithms still need to be improved through using new tools and methods to make the handover decision, as well as taking into account the different viewpoints when choosing the criteria of the handover decision. As some of the existing VHD algorithms, do not exploit the advantages of the multi-criteria nature of the VHD that can give better performance than single criterion algorithms due to the flexible and complementary nature of the different criteriaFurthermore, considering only one or two criteria in the VHD solution is not sufficient to provide a good solution and usually leads to un...
