Ant Colony Optimization (ACO) is a novel bionic evolutionary algorithm for solving complex combinatorial optimization problems. This research approach lies at initial stage at present, and a new adaptive ant algorithm is proposed for the traditional ant algorithm easily appears precocious and stagnation behavior phenomenon in this paper. And the traditional parameter of pheromone of ant colony algorithm...
Wireless sensor networks (WSN) are composed of a large number of sensor nodes which are connected by wireless channels. Some of these sensor nodes are regarded as critical nodes which are responsible for the management of the other nodes in their sphere. Therefore, update of node information must be implemented through these critical nodespsila multicast operation. In this paper, we present a novel...
With the swift development of hardware simulation technology, virtual laboratory environment has appealed more and more attention of educators. In this paper, we develop an interactive virtual laboratory environment for hardware chips application experiment. It provides the students with real expression, convenient operation and powerful simulation capability. Furthermore, interactivity and expansibility...
The purpose of an intellectual answering system is that the system can answer questions automatically. To construct this kind of system, it must collect and store questions and answers organically. The intelligent Q&A system will contain a Q&A library, which is built through the semantic understanding of natural language technology and it will be growing automatically during students question...
Select the close-to-optimal collective algorithm based on the parameters of the collective call at the run time is an important step in achieving good performance of collective operation in base station wireless network. In this paper, we present our Reversed Multicast Tag Collective (RMTC) scheme to optimize the collective routing in base station wireless network. We verify our mechanism in a simulation...
Base station multicast is an important enabling service for the current and future Internet. With the explosive growth of the Internet, a challenging issue facing Base Station multicast is scalability, in particular, the problem of multicast forwarding state and control explosion. In this paper, we propose a new methodology to address the multicast scalability problem for backbone domains - distributed...
Recently, service oriented architecture (SOA) has become a trend of implementing software systems including grids. SOA provides more flexibility for grid users at the service level. In this paper, a scalable service-oriented grid computing architecture utilizing Web-service technology is presented. With the service discovery scheme and resource assignment strategy proposed, the whole architecture...
