Resumé: Abstract: Information-Centric Networking (ICN), presents itself as a candidate for future Internet architecture, is essentially a paradigm shift network focus from host-centric to content-centric. One of the remarkable benefits of ICN is its mobility support compared with IP. However, while consumer’s mobility is naturally supported in ICN, producer mobility is still a challenge. This thesis objective is to design and evaluate a scheme that supports producer’s mobility in ICN within the 5G framework. Further subsidiary objective includes: investigating the impact of the proposed mobility approach on the ICN architecture with focus on congestion control, mobility-awareness and caching. Synopsis: Today’s Internet is based on IP/TCP architecture and has witnessed its success in the past decades. However, the growth in multimedia, social networks, mobile applications and other innovative technologies has driven Internet towards an information distribution network. Therefore there exists a mismatch between the host-centric nature of IP/TCP (naming host with IP addresses) and content-centric nature of today’s Internet applications (naming contents with URL). This mismatch is considered to be the root of many problems in IP/TCP that remain unsolvable (like mobility management and security). In this context, Information-Centric Networking (ICN) has been proposed as a promising future Internet architecture, which reflects better the Internet usage today. ICN is conceptually a simple shift from host-centric paradigm to content-centric paradigm. It is essentially a networking architecture based on named data [1]. - It allows content caching to reduce congestion and improve delivery speed. Data could be retrieved from intermediate cache instead of from the data producer. Thus the traffic goes to the edge, the latency and congestion will always be reduced. - It has simpler configuration of network devices. The communication model is pull- based. Only configuration at one point is needed. - It builds security into the network at the data level. Unlike in TCP/IP, the ICN security is achieved by signing each Data packet. - It supports better network mobility. a remarkable benefit in ICN compared with the original IP architecture. Since interface does not have explicit addresses, changes in a node’s physical location do not imply address change in the data plan, which simplifies the mobility management. Indeed in ICN it is unnecessary to solve problems like connection maintenance, multi-homing that exist in IP’s mobility management. ICN still has plenty of research challenges to be addressed, including: naming, routing, security and trust, application development, mobility, etc. One of the most interesting research areas in ICN is producer mobility. ICN naturally accommodates consumer’s mobility in most cases, it is still a challenge to design special mechanism to deal with producer’s mobility that will be essential to support device-to-device communications and the roll-out of IoT ecosystems. The goal of this thesis is to propose, implement and evaluate a producer mobility support scheme for ICN networks that is fit for 5G networks. Specifically, the candidate is expected to contribute with mobility management protocols that are lightweight, low-latency, and low overhead, and able to scale with the size of the network. The thesis is performed win collaboration with Dr. Luca Muscariello in IRT-SystemX
