Abstract

Due to the mounting requirement for anytime, anywhere network services, we need to integrate diverse kinds of wireless networks. For assisting this integration, the mobile users should be allowed to freely move across networks. The chances of delay in packet transmission, jitter and out of order arrival of packets are predominant when the mobile node gets detached with its home network. This could possibly become a problem when vertical handover needs to be addressed. Proxy Mobile IPv6 (PMIPv6) is a network based mobility management protocol which facilitates the removal of overhead on the mobile node. In order to achieve seamless handover we have proposed a new algorithm which helps to overcome the challenges and issues that can occur during vertical handover. In this paper we have introduced multiple attribute decision making approach for selecting the next access network when the mobile node moves away from its home network. Media independent localized routing is the strategy for accomplishing vertical handover. The proposed algorithm greatly reduces the packet loss and other mobility oriented issues when compared with the prevailing algorithms.
