mSCTP & P2P (2-layered CHORD) supported decentralized seamless mobility framework

Abstract

To get overall advantages of the omnipresent mobile computing, Mobile Node (MN) should be capable to move seamlessly through various networks. But the Internet Protocol (IP) address of the remote Mobile Nodes should be considered in specific time duration, prior to the blockage of services. In 3G, 4G and LAN technologies, it is needed to have a proficient system for location management that accepts the dynamic environments and add issues as failure based on central point, latency and deficiency of consistency. One way is to utilize CHORD for location management that is decentralized, and its key value mapping should better consider to IP mapping, the desired name. But the main problem regarding this mechanism is the existence of chord nodes that are not stable, and this creates instability in the framework. Nodes having low computation abilities can retard the look-up technique and thus ends the active session. Here we give a solution to the issue, utilizing two-layered CHORD design against single Layered CHORD. Nodes having high computation capabilities and stability will perform as location servers, and will be liable for saving and allocation the temporary locators that is IP address of the remote MN. Appropriation of suggested framework is analyzed utilizing analytical analysis in distinguished with current CHORD mobility protocol. The said way can stabilizes the framework using its de-centralizing feature, yet intact.
