Internet of things mobility over information-centric/named-data networking

Information-centric networking (ICN) is a content-oriented network that uses content instead of traditional IP addresses, it facilitates the content retrieval and calculates downstream paths without the need of an optimal topology. ICN inherits mobility support features in its baseline design. Since the Internet of Things (IoT) faces major problems in supporting mobility management over IP, we believe that ICN would represent a major element in scalable IoT networks. This article discusses the use of ICN as a communication model in IoT environments, focusing on solving the mobility issue. Thus, we survey the relevant work that studies the merger between ICN and IoT, and describe the emergence, evolution, and state-of-the-art mobility approach. This article also presents discussions on major scalability challenges when using ICN as a communication enabler for mobile IoT and highlights key designs and guidelines.
