A NOVEL SECURE HANDOVER MECHANISM IN PMIPV6 NETWORKS

The Internet Engineering Task Force (IETF) proposed proxy mobile ipv6 (PMIPv6) is a very promising network based mobility management protocol. There are three entities LMA MAG and AAA server required for the proper functioning of PMIPv6.. In PMIPv6 Networks having many disadvantages like signaling overhead , handover latency ,packet loss problem and long authentication latency problems during handoff. So we propose a new mechanism called SPAM which performs efficient authentication procedure globally with low computational cost. It also supports global access technique using ticket based algorithm. Which allows user’s mobile terminals to use only one ticket to communicate with their neighbor Access Points? This algorithm not only reduces the mobile terminal’s computational cost but also provides user ID protection to protect user privacy. Through this technique, it can implement handover authentication protocol, which in turn results in less computation cost and communication delay when compared with other existing methods
