An Agent-Based Framework for Supporting QoS in Grid Environment

The role of multimedia application in our life has dramatically increased in the last few years. Multimedia streaming is more significant than downloading ways in multimedia applications from bandwidth and delay reasons. Multimedia contents are in nature distributed in nodes of grid. Streaming media are still not well resolved in grid environment. This thesis proposes an agent-based framework for grid called GridMSS. The main characteristics of that are highlighted by its promising QoS supporting such as accessibility, low latency and reliability, its flexibility and packet allocation mechanisms of nodes. Here an agent searches for requested contents by communicating with other agents and in order to retrieve contents related to users´ query without delay, an allocation algorithm is performed according to available bandwidth of each node. GridMSS provides a high performance contents streaming framework for a large population of users and ensures the QoS in terms of accessibility, low latency and reliability. The empirical results showed that the framework was efficient enough to be used in grid environments.
