Abstract

Resource management is one of the important issues in the efficient use of grid computing, in general, and poses specific challenges in the context of ad hoc grids due to the heterogeneity, dynamism, and intermittent participation of participating nodes in the ad hoc grid. In this paper, we consider three different kinds of organizations in an ad hoc grid ranging from completely centralized to completely decentralized (P2P). On the basis of self organization mechanisms, we study the effect of the neighborhood degree of a node for finding resources on the efficiency of resource allocation. We investigate the message complexity of each organization and its corresponding efficiency in terms of task/resource matching and the response time. We show that the intermediate state of the ad hoc grid with multiple adaptive matchmakers outperforms both a completely centralized and a completely decentralized (P2P) infrastructure.
