Cost-effective resource segmentation in hierarchical mobile edge clouds Special Feature on Future Network-Research Article

Ming-shuang JIN, Shuai GAO, Hong-bin LUO, Hong-ke ZHANG

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 9,   Pages 1209-1220 doi: 10.1631/FITEE.1800203

Abstract: The fifth-generation (5G) network cloudification enables third parties to deploy their applications (e.g., edge caching and edge computing) at the network edge. Many previous works have focused on specific service strategies (e.g., cache placement strategy and vCPU provision strategy) for edge applications from the perspective of a certain third party by maximizing its benefit. However, there is no literature that focuses on how to efficiently allocate resources from the perspective of a mobile network operator, taking the different deployment requirements of all third parties into consideration. In this paper, we address the problem by formulating an optimization problem, which minimizes the total deployment cost of all third parties. To capture the deployment requirements of the third parties, the applications that they want to deploy are classified into two types, namely, computation-intensive ones and storage-intensive ones, whose requirements are considered as input parameters or constraints in the optimization. Due to the NP-hardness and non-convexity of the formulated problem, we have designed an elitist genetic algorithm that converges to the global optimum to solve it. Extensive simulations have been conducted to illustrate the feasibility and effectiveness of the proposed algorithm.

Multi-discipline Forecast and Warning Engineering System on Sediment-related Disasters

Yao Xuexiang,Xu Jing

Strategic Study of CAE 2004, Volume 6, Issue 6,   Pages 9-14

Abstract:

Sediment-related disasters are caused by various factors. A multi-discipline and multi-department cooperation is important to construct the warning engineering system on sediment-related disasters. Most of the sediment-related disasters are induced by rainfall. Based on the regressive relationship between the disaster occurrence and rainfall, a meteorological-statistical potential forecast model for sediment-related disasters is developed as part of a joint project undertaken by China Meteorological Administration (CMA) and Ministry of Land and Resource ( MLR). The forecast has been launched into operation since June 1，2003，when a nationwide sediment-related disasters warning system via public media was set up by CMA and MLR. In this paper the forecast and warning system is reviewed and some valuable suggestions are presented.
