Mobility Support for Content Centric Networking: Case Study

The current Internet architecture was not designed to fullfil the requirements of nowadays services, therefore it faces a lot of challenges. There exist several projects, which target to redesign the Internet architecture completely. Content Centric Networking (CCN) is one of them. CCN is based on naming content instead of hosts. It has been shown that CCN can also support point-to-point conversions, for example voice calls. However, it has not been defined how node mobility can be achieved in such a real-time scenario with strong time constraints. This paper illustrates the arising problems of mobility in CCN for real-time applications and proposes three different solutions. The results and the analyses show that the presented approaches can reduce the delay time and also reduce signaling overhead.
