Using the Internet Protocol, demand appeared to connect devices to the network even while devices are continuously changing their points of attachment. In legacy internet infrastructures, the handover results broken connections and terminatid sessions. However in the context of future mobile generations, this is not allowed. The ultimate goal is to reach the mobile node under the same address, wherever it is with lack of connectivity anytime, anywhere.
Trends also show the merge of different access technologies within the umbrella of the IP.
This view was followed by the wade proliferation of IP and will be followed by deployment of IP mobility extentions. The mobility handling methods have to be examined whether a particular scheme is about the mobility management if a single mobile nie, or an entire moving network. These questions are answered by Mobile IPv4, Mobile IPv6, Proxy Mobile IPv6 for a mobile node moving. The goal of NEMO technology is managing moving network scenarios a network handover.
In spite of Mobile IPv6, a Proxy Mobile IPv6–ready devices do not have to have special TCP/IP stack to be able to use the benefits of mobility. Mobile nodes in a PMIPv6 architecture do not know about their movments within the IP topology. It is called network-based mobility management and implements an operator-centric solution for the IP mobility problem space.
In my thesis, I examine PMIPv6 under the scope of the MIPv6, and its operator-centric approaching. I have designed and implemented four different testenvironments in which I illustrate and analyze the bevavior of theseadvanced IPv6-based mobility management protocols.
