Vertical Handover Decision Schemes Using SAW and WPM for Network Selection in Heterogeneous Wireless Networks
Source: Global Journals
Seamless continuity is the main goal and challenge in Fourth Generation Wireless Networks (FGWNs), to achieve seamless connectivity "HANDOVER" technique is used, Handover mechanism 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, Simple Additive Weighting method (SAW) and Weighted Product Model (WPM) are used to choose the best network from the available Visitor networks (VTs) for the continuous connection by the mobile terminal.
