Mobile edge computing is an emerging computing paradigm boosting resource-demanding and delay-sensitive applications through deploying computing infrastructures at the edge of the Internet nearby mobile requesters and users. In an Internet of Vehicles (IoV) environment, Vehicular Edge computing (VEC) is capable of exploiting network edge devices, in terms of, e.g., Roadside Units (RSUs), for predictive content caching for optimizing quality-of-experience (QoE) of nearby content requesters based on content popularity analysis, it remains a great challenge to accurately predict content popularity of mobile requesters and appropriately cache required content with low miss rate accordingly in a VEC environment with high user mobility and dynamics. To address this challenge mentioned above, in this paper, we propose predictive content popularity-aware approach, i.e., KM_SVD++, to edge caching in an VEC environment. The proposed approach is capable of achieving high hit rate of mobile content requestors in VEC and low latency of content delivery by leveraging a Kalman filtering model for predicting locations of vehicles and a SVD++ one for yielding decisions for cache deployment and replacement. We conduct extensive simulations as well to prove its effectiveness.

In software-Defined Networking (SDN), the positioning of controllers and the division of switches determine the upper limit of the network's responsiveness to network events. However, highly dynamic satellite networks pose a significant challenge to the controller placement problem. The difficulty is to achieve efficient control over a long period of time with low overhead. Existing methods mostly perform computations independently and greedily in each time slot, leading to frequent changes in the controller placement and the control relationships between controllers and switches. In this paper, we present a comprehensive model to measure the control plane overhead. By defining migration overhead and anticipated overhead to ensure the continuity of control strategies, we formulate the controller placement problem in software-Defined Low Earth Orbit (LEO) satellite networks as an optimization problem. To tackle this issue, we draw inspiration from hierarchical clustering techniques and introduce a heuristic algorithm named Hierarchical Clustering-based Minimizing Overhead Algorithm (HCMOA). Evaluations of our simulation system show that HCMOA significantly outperforms relevant approaches in terms of control overhead and average response latency.
