In this paper, PHMIPv6 proposes to select the node with the highest signal strength as the partner node. and CSA- PHMIPv6 for which mobile hosts select partners with whom communication can last for a sufficiently long time by employing the Link Expiration Time (LET) parameter. The internet-based applications have transformed the mobile networks into all IP configuration frameworks. IP does not support mobility. Mobile IP is an Internet Engineering Task Force (IETF) standard communications protocol that is designed to allow mobile device users to move from one network to another while maintaining a permanent IP address.
