Vertical Handover Decision Algorithms in Multi-Wireless Network Systems

The premise of having several network systems consists of different access technologies. Network correspondence happens when two wireless schemes exchange information over the network. A moving cell-phone device could achieve vertical handover operation when receiving signal strength (RSS) from network. Using one of wireless services may interrupt with other service and cause unbalanced network load, or it may cause incompetent vertical handover. This research improves vertical handover decision algorithm for multiple wireless network service. It is preceded with comparing three wireless communication interfaces, which are Wireless Local Area Network (WLAN), Worldwide Interoperability for Microwave Access (WiMAX), and LongTerm Evolution (LTE). The study base on three types of priority algorithms to make a vertical handover decision (VHD), they are: equal, mobile, and network priority. VHD algorithms are fundamental segments to the engineering of the anticipated Fourth Generation (4G) heterogeneous wireless networks. These algorithms should be intended to give the required Quality of Service (QoS) to a wide scope of uses while permitting consistent wandering through a host of access network fees. The results show that the proposed algorithm for handover decision calculation beats the customary network decision calculation as far as handover number likelihood and the handover disappointment likelihood. What's more, it is seen that the network need handover decision calculation creates better outcomes contrasted with equivalent need and mobile need handover decision calculation. Lastly, the simulation outcomes are approved using explanatory model.
