Distributed Cooperative Sensing in Cognitive Radio Networks: An Overlapping Coalition Formation Approach
TL;DR: In this article, a distributed cooperative sensing (DCS) algorithm was proposed in which the SUs self-organize into a desirable network structure with overlapping coalitions, and the simulation results show that the proposed overlapping algorithm yields significant performance improvements.
Journal ArticleDOI
A Dynamic Edge Caching Framework for Mobile 5G Networks
TL;DR: This framework allows an edge node to authorize the legitimate users and dynamically predicts and updates their content demands using the matrix factorization technique, and can adopt advanced optimization methods to determine optimal content to store so as to maximize its revenue and minimize the average delay of its mobile users.
Proceedings ArticleDOI
Impact of packet loss on power demand estimation and power supply cost in smart grid
TL;DR: A model to optimize the cost of power supply given demand uncertainty is presented and the impact of packet loss performance on the optimization of cost for power supply in smart grid is model and analyzed.
Journal ArticleDOI
Secrecy Analysis on Network Coding in Bidirectional Multibeam Satellite Communications
TL;DR: The confidentiality issue in a bidirectional satellite network consisting of two mobile users who want to exchange message via a multibeam satellite using the XOR network coding protocol is studied to maximize the sum secrecy rate by designing the optimal beamforming vector along with optimizing the return and forward link time allocation.
Journal ArticleDOI
Electric Power Grid Restoration Considering Disaster Economics
TL;DR: This paper provides a prototype and a proof of concept for utility companies to consider economics of disaster and include unit commitment model into the post-disaster restoration process.
