In order for travelers to arrive at their destination comfortably, it is important that they plan their trip carefully. Our motivation in this paper is to free the traveler from tedious planning tasks. Several studies and applications have been proposed to help travelers plan their trip according to explicit preferences, but most ignore implicit preferences. For the first time, to the best of our...
As modern computer systems become increasingly complex in infrastructure and usage, the demand for capabilities of detecting anomalous behavior has grown urgent. Although techniques for point anomaly detection have been proposed and adopted in practice, behavior anomaly detection still lacks effective approaches due to its inherent complexities. We present a new anomalous behavior detection model...
A stable and optimal overall performance is always the target for any process engine. In this paper, we introduced a dynamic matrix control based service process engine. It is built on the Jini platform and employs Jini services to provide functions for a service process engine. The process engine will estimate each client request workload by a heuristic algorithm. According to the estimated workload...
Mesh-based overlay has emerged as a promising scalable solution for distributing live video stream, but it relies on random selections of neighbors, without optimizing the overlay by exploiting peer location and bandwidth, which leads to high delay incurred during video diffusion. In order to reduce the diffusion delay, we design a Location and Bandwidth (LB) balance overlay with hierarchical structure,...
Distributed Constraint Optimization Problem (DCOP) is a framework that recently emerged as one of the most successful approaches for coordination in Multi-Agent system. Dynamic Programming Optimization (DPOP) is an algorithm which requires only a linear number of messages, thus introducing exponentially less network overhead than other search algorithms when applied in a distributed setting. In DPOP...
