Survey on key technologies of covert channel in ubiquitous network environment by Fenghua LI, Chaoyang LI, Chao GUO, Zifu LI, Liang FANG, Yunchuan GUO

“…In the ubiquitous network environment, covert channel bypasses the system’s security strategy to transmit covert information by modifying the system’s shared resources, which poses a serious security threat to the computer and network system.The researches on covert channel in ubiquitous network environment were summarized and analyzed from three aspects of measurement, construction and detection.First, the typical covert channel metrics including the capacity, robustness, anti-detection, regularity and shape were summarized.Second, the construction technologies of covert channel were summarized and analyzed from six aspects of resource sharing, capacity, robustness, anti-detection, advantages and disadvantages in the first time.Third, the detection technologies of covert channel were compared and analyzed from five aspects of the type of covert channel, accuracy, whether it can be blind detection, the advantages and disadvantages.Finally, the development trends of covert channel were summarized and future research directions were prospected.…”

Mobile edge computing and application in traffic offloading by Jianmin ZHANG, Weiliang XIE, Fengyi YANG, Zhouyun WU, Liang XIE

“…Mobile edge computing（MEC）makes it possible to deploy and provide service locally,which is close to the users,by enabling the IT and cloud computation capacity at the radio access network (RAN).Thus,MEC can improve the quality of experience (QoE) by reducing the latency,and decrease the network operation cost through reducing backhaul capacity requirement.Meanwhile,based on the network context information (location,network traffic load,radio information,etc) exposure to applications and services,MEC can further improve the QoE of user and provide the platform to third-party partners for application and service innovation.Besides the introduction of MEC,the detailed MEC platform was presented.Furthermore,the traffic offloading solution based on MEC was proposed and compared with the solution of local IP access and selected IP traffic offload (LIPA/SIPTO).In addition,the problems and challenges of the MEC were also discussed in detail.…”

Mobility model detection method based on birth and death model in DTN environment by ENGGuang-hong D, AOWan-hua C, HANGJian Z, HENGXiong C, ENGLi F

“…A mobility model detection method based on birth and death model (MMD-BDM) in DTN environment was proposed.It first computed the connected channel capacity of sampling times according to the data traffic during the data transfer process,and then constructed the time varying intercommunication metrics at local,which composed of channel capacity between local node and others.Based on these,the connection birth and death mode of nodes based on connected edges was deduced,and then the birth and death features of the connected nodes was analyzed to detect the mobility model,which used to improve the routing strategy during the packages deliver process.Ultimately,the mobility model detection method was put into use in spray and wait routing (SWR) method and random network coding routing (RNCR) method to experiment,the simulation results show that,it can improve the opportunity routing performance of the data deliver rate and transfer latency in DTN environment.…”

Research and Design of Flood Discharge and Energy Dissipation Structures of Datengxia Hydro Project by TAN Zhijun, PAN Minghong

“…The design of flood discharge and energy dissipation structures is important and is the primary research problem in the layout of hydro projects,which involves the problems of discharge capacity,cavitation of flow surface,water aeration,and sediment abrasion and scouring of downstream riverbeds.For the Datengxia hydro project,its maximum discharge capacity of flood discharge structures reaches 66,200 m³/s,and the Froude number of energy dissipation structures is low.Therefore,the scheme of bottom outlets for flood discharge and surface outlets for drift discharge is adopted for flood discharge structures,and the underflow energy dissipation mode of the secondary stilling basin is adopted for energy dissipation structures.As flood discharge structures mainly adopt the bottom outlets for flood discharge,and the radial gate bears huge water thrust,the steel beam is selected as the radial gate support,which solves the difficulties in engineering design and provides a reference for similar projects.…”
