Previous studies of botnet size basically focus on details and concreteness instead of nature of problem due to polymorphic, versatile, complex behavior of botnet and partial observation on network. This paper investigates the nature of botnet size, upon which four(More)
With the rapid expansion of the Internet, network security has become more and more important. IDS (Intrusion Detection System) is an important technology coping network attacks and is of two main types: network based (NIDS) and host based (HIDS).

For an efficient network security and management it's required to have a better understanding of its structure and traffic caused by different elements (IP hosts). There is a need to improve systems(More)
With the rapid development of the Internet, big data era comes, and the Internet, Internet of things, vehicular networks are blending mutually. We need to study and solve the problem of how to process the big data. In the field of traffic, forecasting traffic flow precisely in real time is the prerequisite and basis to process the big data effectively.(More)
