Towards seamless mobility in ICN : connectivity, security, and reliability

Xuan Zeng 1
Abstract : With the proliferation of mobile devices, mobility becomes a requirement and a compelling feature for 5G. However, despite tremendous efforts in the last 2 decades to enable mobility in IP network, the solutions are mostly anchor-based and inefficient. In this context, Information-Centric networking (ICN) is proposed. While ICN has some native support of mobility, other architectural challenges remain unsolved to achieve seamless mobility. The thesis explores 3 main challenges of such and contributes novel solutions. First, to solve producer mobility, MapMe, a micro mobility management protocol supporting latency sensitive traffic is proposed. MAP-Me is anchorless and preserves key ICN benefits. Simulation results show that MAP-Me outperforms existing work in user performance while retaining low network overheads in various network conditions. Second, we investigate security in producer mobility. We focus on prefix hijacking attack, which is a basis of several attacks. To prevent prefix hijacking, we propose a light-weight and distributed prefix attestation protocol based on hash-chaining. First results show significant improvement in verification overhead. It is resistant to replay-based prefix hijacking. Finally, additional transport-layer mechanisms are needed in mobile ICN. To this aim, we investigate alleviating the adverse effect of wireless/mobility loss on congestion control. We propose WLDR and MLDR for in-network loss detection and recovery to facilitate congestion control. Simulation results show a significant reduction in flow completion time (up to 20%).
