MULTI NETWORK HANDOVER DECISION USING EXTENDED MULTI CRITERIA DECISION MAKING TECHNIQUE

Abstract: In a heterogeneous environment various wireless networks are coexisting simultaneously. This environment is formed by integrating various radio access technologies like Wireless in Local Loop (WLL/WLAN), WirelessWwide Area Network (WWAN), Cellular etc. These technologies offer users to connect to network at anytime and anywhere. Now the mobile devices are equipped with multiple interface terminals so that the devices can select the best network. Selecting a suitable network which satisfies the different need is very complex task in heterogeneous network. The decision is based on different network criteria and user’s information. In this paper a handover decision technique is presented which is used to select most appropriate network among various networks.

Keywords:

Heterogeneous wireless network, vertical handover, seamless mobility, mobile node received signal strength,
