Pervasive computing, as a new branch in the eld of distributed computing, has received wide contribution from dierent researchers. In this novel computing model, a vast range of computational and communication resources, along with other types of service, are gathered under a single system image based on certain predened criteria. To create a transparent environment and provide end-users with the illusion of the local availability of multiple resources, some kind of manager is needed to coordinate the tasks and their required resources. The resource management system is mainly responsible for a balanced distribution of available resources among dierent tasks. Devising ecient resource discovery and dissemination algorithms is, hence, an important step towards preparing the bases for a resource centric management package. In this article, the aim is to provide two algorithms for this problem, using mobile agents. The proposed resource discovery algorithms use two dierent hierarchical and at approaches. The simulations show a good performance for both of the proposed models; however, the hierarchical algorithm shows better results, based on some of the introduced factors
