Abstract:Internet service providers (ISP) are offering 4G network services through several
wireless technologies such as WLAN, WiFi, WiMAX, LTE, etc. Thus, multimode devices
will be able to manage communication links with different networks and support seamless
mobility in these networks. To make decision for network selection during handoff, this paper proposes an
Agent based vertical handoff decision algorithm that motivates users to periodically obtain the decision parameters
and to identify optimal cost for decision function. The proposed handoff decision scheme uses agent
technology. Link Monitoring Agent (LMA) is used to identify the decision parameter. The Handoff decisionmaking
agent evaluates the decision function. These agents interact with each other in order to accelerate the
handoff decision operation during vertical handoff.
