Super point is a special host in network which communicates with lots of other hosts in a certain time period. The number of hosts contacting with a super point is called as its cardinality. Cardinality estimating plays important roles in network management and security. All of existing works focus on how to estimate super point’s cardinality under discrete time window. But discrete time window...

Graph coloring is one of the most famous computational problems with applications in a wide range areas such as planning and scheduling, resource allocation, pattern matching. So far are mostly studied on static graphs, which often stand contrast to practice where data inherently dynamic. A temporal graph has an edge set that changes over time. We present natural extension classical problem. Gi...

Existing ad hoc routing protocols are either unicast or multicast. In this paper we propose a simple extension to the Dynamic Source Routing Protocol (DSR) to cater for group communications where all node addresses are unicast addresses and there is no single multicast address. The proposed sliding window protocol for multiple communications results in significant improvement in total packet de...

We study the space complexity of querying languages over data streams in the sliding window model. The algorithm has to answer at any point of time whether the content of the sliding window belongs to a fixed regular language. For regular languages, a trichotomy is shown: For every regular language the optimal space requirement is asymptotically either constant, logarithmic, or linear in the si...

System states space based on Kripke structure can be exhausted by model checking, thus system key property described by temporal logic can be automatically verified. Presently model checking has been widely used in hardware validation and network protocol analysis. Sliding window protocol is a classical receive-send protocol, which is used in TCP/IP protocol group. In this paper, we propose the...

This paper examines the causality between concentration in banking industry and economic growth by using data across 15 countries named in "Iran outlook in 2025", over the period 2004-2011. Our aim is to assess whether the economy grows more or less rapidly in areas where the banking sector is more concentrated. The topic is motivated by the fact that the causality between concentration in bank...
