Network virtualization has been regarded as a core attribute of Future Internet. To improve the quality of virtual network, it is important to diagnose the faulty components quickly and accurately. Recently more and more researches focus on end-user fault diagnosis, which can fit incomplete knowledge and dynamic challenges. In this paper, we present a fault diagnosis system called DiaEO in virtual...
To solve the coverage and quality problems caused by cell outage in LTE networks, this paper proposes a distributed self-organizing networks management architecture and a distributed cell outage compensation management mechanism. After detecting and analyzing the outage, a cell outage compensation algorithm based on reference signal power adjustment is proposed. The simulation results show that the...
A system of transmission line tower anti-theft monitoring based on video difference analysis is designed in this paper. Gaussian Mixture Model is firstly used to create dynamic background model. Then the moving objects can be extracted effectively with the background subtraction. SVM is used to detect moving targets on the quick identification. Finally, Based on regions and characteristics method,the...
