As streaming media over the Internet becomes popular, caching proxy has become increasingly important. Nowadays, caching proxy has turned into a standard technique, which is widely deployed on the Internet to reduce client-perceived delay and network traffic. In this paper, we propose a cluster-based streaming caching proxy architecture in which the local network has a number of independent cac...

Due to high latency of the Internet, it becomes a challenge to access large and widely distributed data quickly and efficiently on data grids. Replication is a process to address this issue, by storing data in different locations to reduce access latency and improve data locality. However, because of the limited storage capacity, a good replica replacement algorithm is needed to improve the eff...

A considerable problem in competitive trade world is choosing the best supply chain. As a result in much more serious circumstances of competitions looking for the best supplier for manufacturing, for preparing raw material, is very significant. Meantime suppliers have different scenarios to be fulfilled, such as changing selection variables like lead-time, transportation cost and transportatio...

In this paper we present a high performance cache replacement algorithm called Dueling Segmented LRU replacement algorithm with adaptive Bypassing (DSB). The base algorithm is Segmented LRU (SLRU) replacement algorithm originally proposed for disk cache management. We introduce three enhancements to the base SLRU algorithm. First, a newly allocated line could be randomly promoted for better pro...

This is an adoptive design of ant colony system and has been generalised to AGV transport system, predetermined targets replacement results has been evaluated simulating four AGV in Mat lab by Particle Algorithm and fuzzification and simulating the operative environment with regard to constant velocity and different results has been compared to each other by changing robots’ location and replac...

Grid computing is one of the fastest emerging technologies within the high performance computing environment. Grid deployments that require access to and processing of data are called data grids. They are optimized for data oriented operation. In a data grid environment, data replication is an effective way to improve data accessibility. However, due to limited storage, a replica replacement st...
