Distributed Denial-of-Service (DDoS) attacks are a great threat to the Internet. Enabling accurately detection of Distribute Denial-of-Service attacks is important because it is the foundation of defense against the attacks. In this paper, we focus on the distribution difference of the packet size between normal traffic flows and attack traffic flows and propose an entropy-based detection measurement...
With the development of Mobile Internet and the rapid growth of mobile social communication and mobile video, the network scale has been growing rapidly and the energy consumption is too huge to be ignored. Current estimates indicate that Information and Communication Technology (ICT) is responsible for a fraction of the global energy consumption ranging between 1% and 2%, among which, the consumption...
In order to solve the balance problems between efficiency and accuracy encountered in content-based video retrieval, in this paper, we propose firstly a video retrieval scheme based on coarse granularity. To achieve the coarse-grained video retrieval, we use inverted index. Further, we expose an improved BLAST algorithm to realize fine-grained retrieval of video fingerprint. Finally, simulation results...
Existing virtual network mapping algorithms does not consider resource consumption of intermediate node on communication path usually. Minimum resource consumption or shortest path of physical network is regarded as objective, thereby leading to bottleneck due to insufficient resource of intermediate node on communication path, and affecting performance of the whole physical network and subsequent...
The Internet is dramatically evolving and creating various connectivity methodologies. The Internet of Things (IoT) is one of those methodologies which transform current Internet communication to Machine-to-Machine (M2M) basis. Hence, IoT can seamlessly connect the real world and cyberspace via physical objects that embed with various types of intelligent sensors. A large number of Internet-connected...
A wireless distribution implementation of smart distribution network is presented in this paper, and this is commonly thought as one of the key technologies of Internet of Energy. Several communication technologies applied in the power distribution are analyzed, the wireless distribution network (WDN) is designed with the software defined network concept, and the control plane is used as a common...
