A novel two-stage design and the eco-IDsC (Energy Cost Optimization-IDC) algorithm is proposed to exploit the temporal diversity of electricity price and dynamically schedule workload to execute on IDC servers through an input queue.
Performance and Reliability Analysis of IEEE 802.11p Safety Communication in a Highway Environment
This paper focuses on the analysis of the 802.11p safety-critical broadcast on the CCH in a VANET environment and improves the existing work by taking several aspects into design consideration and extensive performance evaluations based on the NS-2 simulator help to validate the accuracy of the proposed model.
Hierarchical Gating Networks for Sequential Recommendation
A hierarchical gating network (HGN) integrated with the Bayesian Personalized Ranking (BPR) to capture both the long-term and short-term user interests is proposed, and the experimental results demonstrate the effectiveness of the model on Top-N sequential recommendation.
