An overview of the factors affecting handovers and effective highlights of handover techniques for next generation wireless networks

Mobility is the need of the hour computing and communication devices of today are ubiquitous and work in heterogeneous environment. Wordings, for example, Always Best Connected, Seamless Mobility are considered as key highlights of Next Generation Wireless Networks (NGWN). The test for Next Generation Wireless devices is guaranteeing end-to-end availability via consistently relocating between Heterogeneous wireless technologies (viz. Wireless LAN, WiMax, Cellular, UMTS, and LTE and so forth.) This procedure of handover between various wireless technologies alluded to as Vertical Handovers/Handoffs has critical significance among industry and the scholarly world scientists. The prime target of this paper is to give a one-stop literature store on nuts and bolts of Handovers, Classifications, Algorithms, Factors impacting Handovers and alluring highlights of Handover mechanisms for NGWN.
