Internet of things (IoT) has been researched in recently years. The Savant as a midware provides the data collecting and pre-processing for the IoT applications. Data grid can aggregate the resources in the IoT. Using data grid to build the Savant enables the Savant manage large scale data and optimizes the efficiency of the resources in IoT. In this paper, the data in the IoT is classified, and a...
Applications can be submitted as jobs in grid. Grid jobs usually comprise the scenarios of file stage-in, execution and file stage-out. These scenarios always run in batch mode. It leads to the waiting of the computational resource for data transfer and limits the performance of the grid application, especially when the application is data/communication intensive. Utilizing the file sharing function...
The vehicle routing problem with time windows (VRPTW) is a well-known and complex combinatorial problem, which has received considerable attention in recent years. In this paper, an effective meta-heuristics for VRPTW was designed to minimize the vehicle number and total travel distance. Performances are compared with other heuristics appeared in the literature recently by the bench-mark data sets...
With the increasing network security accidents, intrusion detection systems (IDS) have been an indispensable part of information system. As a popular light network intrusion detection system, Snort has been a focus in research field. In this paper, dynamic adjustment algorithm is applied to the improvement of rule matching based on the analysis of original mechanism of Snort. Additionally, further...
One of the challenging problems in grid environment is the choice of destination nodes where the tasks of the application are to be executed. Therefore, resource prediction is a crucial direction for job scheduling system and grid users. In this paper, Nu-support vector regression (v-SVR) is applied to solve resource prediction problem. The method of parallel multidimensional step search is also introduced...
