A Novel Resource Dissemination and Discovery Model for Pervasive Environments Using Mobile Agents

Pervasive computing has been the new buzz word in the distributed computing field. Vast range of heterogeneous resources including different devices, computational resources and services world wide are virtually summoned under agreed conditions to form a single computational system image [1].In this approach a central controller is needed to coordinate the resources which is called the resource management system (RMS).A typical RMS is responsible for three main jobs including matching, scheduling and executing received requests based on suitable and available resources. Regarding the matching module, resource dissemination and discovery forms the main part. In this article we introduce two new approaches to tackle this problem using the mobile agents. The different strategies are dividend into hierarchical and non-hierarchical models. The performed simulations show a better performance for the hierarchical approach compared with the other model.
