Executive Summary

Seamless continuity is the main goal and challenge in Fourth Generation Wireless Networks (FGWNs), to achieve seamless connectivity "HANDOVER" technique is used, Handover mechanisms are mainly used when a Mobile Terminal (MT) is in overlapping area for service continuity. In heterogeneous wireless networks, main challenge is continual connection among the different networks like WiFi, WiMax, WLAN, WPAN, etc. In this paper, vertical handover decision schemes are compared and Grey relational analysis is used to choose the best network from the available Visitor neTworks (VTs) for the continuous connection by the mobile terminal. In this paper, the authors' mainly concentrated to the handover decision phase and to reduce the processing delay in the period of handover.
