- 摘要：Network security risk assessment is an important means of acquiring and mastering the current and future state of network, which is of great significance to maintain the safe operation of the network. An improved risk assessment method based on Markov game that has simply changed the past was presented, in which the risk status of the network assets were classified into fixed categories. Depending on the game relationship between vulnerabilities fixing and threat attacking, this method has more detailed characterization of the network risk. Network attacks and vulnerabilities were sorted, which reduced the state space, making the scale of model input greatly reduced, improving the assessment of large-scale network efficiency. In addition, the relative importance of the hosts was taken into account to distinguish the contribution of different hosts on the network risk. Simulation results demonstrate the feasibility and effectiveness of this method.关键词：network security;risk assessment;Markov game;vulnerability720|1646|0更新时间：2024-06-05

- 摘要：A novel communication service methodology, virtual real-time service, was proposed to discover and utilize the rich temporal and spectrum resource hidden in the negative time axis. Thanks to the delay tolerance of embedded wireless pushing,it could help to unify the content demand of different users,so as to achieve significant spectral and energy efficiency gains of wireless multicasting. The three extensions of cognition object, time scale, and coordination range, induced by virtual real-time service were described. The consumption of computation and storage resource was a cost to be paid for the gains of the energy and spectral efficiency.Hence,the multi-unit collaboration of computation （including cognition）, storage, and communications units was highly desired to minimize the cost of computation and storage resource, while maximize the energy and spectral efficiency gains. The proposed scheme holds the promise of overcoming the stringent restrain on the spectral efficiency,which is caused by the current communication architecture and its underlying theory. The union of its two main characteristics, namely, time non-homogenous transmission and multi-unit collaboration,are expected to form a paradigm-shift theory on time non-homogenous multi-unit collaboration communications.关键词：wireless communication;virtual real-time service;multi-unit collaborative communication;spectrum efficiency;cognitive wireless network;5G388|936|0更新时间：2024-06-05
- 摘要：Two-tier macro-femto-cellular networks have initially been proposed as a solution to the poor indoor coverage problem, but they are also capable of substantially reducing the overall energy consumption. However, the cross-tier and co-tier interference have to be carefully controlled with the aid of specific radio resource allocation and optimization techniques. A mobile cloud computing management architecture was proposed firstly. Then novel concept of spatial transmission efficiency for PtP radio link was first introduced with several existing efficiency metrics compared. An analytical model was conceived and a radio resource management algorithm based on LTE-A mobile cloud computing was designed. In order to achieve the optimal solution quickly, a rapid convergence of the iterative algorithm was designed. Simulation result shows the proposed algorithm achieves the maximum of system energy efficiency with a superior tradeoff with system throughput.关键词：mobile cloud computing;two-tier macro-femto-cellular network;green wireless communication;radio resource allocation;LTE-A380|612|0更新时间：2024-06-05

- 摘要：The real-time video services in wireless networks are fragile to the dynamic network environment.Therefore, proper buffering management techniques are adopted to mitigate the impact of network fluctuation on user experiences. An adaptive buffer management algorithm based on queue prediction was proposed for wireless video streaming applications.

The experiments were conducted to validate the proposed algorithm.The experimental results show that this method is able to adaptively adjust buffer size and playout rate according to network fluctuations,which reduces the interrupt frequency and the number of lost frame effectively.关键词：adaptive buffer management;queue prediction,;buffer status;delay contro283|463|0更新时间：2024-06-05

- 摘要：iMusci Karaok is a service on IPTV developed and operated by China Telecom. It is needed to introduce active personalized push approach of content in order to improve user experience, due to higher cost of remote controller than PC and mobile phone. However, Karaok is a household service, and is ununiform to identify users on server side and terminal side, which will bring inaccurate result when normal recommendation algorithm is adopted. Meanwhile, traditional recommendation algorithm has defects of Matthew effect and cold reboot, which will decrease user experience. To tackle such problems of user experience, the recommendation algorithm was selected and optimized by combination of content label so as to increase recommendation objectively. This research is aiming at enhancing user experience effect rather than algorithm complexity.关键词：association rule;label;personalized push;AHP;weight;SVD;independence test;Matthew effect367|589|0更新时间：2024-06-05
