With the rapid growth of network traffic volumes in terms of the content and mobile data, how to cope with these two new trends of Internet has been widely discussed. Among related solutions, Named Data Networking (NDN) is aimed to achieve highly effective content distribution. Besides, the mobility support is also one of its important research contents, attracting great attentions. Thus, in this paper, we provide a survey on the mobility support in NDN. Specifically, we firstly present the problem statement for both mobile producers and consumers in NDN, then classify and illustrate mechanisms of existing schemes based on their characteristics. Finally, we discuss the advantages and disadvantages of these countermeasures.

Mobile-Edge Computing (MEC) is a novel and sustainable network architecture that enables energy conservation with cloud computing and network services offloading at the edge of mobile cellular networks. However, how to efficiently manage various real-time changing security functions is an essential issue which hinders the future MEC development. To address this problem, we propose a fuzzy security service chaining approach for MEC. In particular, a new architecture is designed to decouple the required security functions with the physical resources. Based on this, we present a security proxy to support compatibility to traditional security functions. Furthermore, to find the optimal order of the required security functions, we establish a fuzzy inference system (FIS) based mechanism to achieve multiple optimal objectives. Much work has been done to implement a prototype, which is used to analyze the performance by comparing with a widely used method. The results prove that the proposed FIS mechanism achieves an improved performance in terms of Inverted Generational Distance (IGD) values and execution time with respect to the compared solution.
