Abstract

In this paper we investigate the market economy of a Peer-to-Peer network for Grid Computing. We present a simulation of p2p network where nodes either require or offer resources, which can be thought as CPU time for example. We examine the market behaviour of the P2P network for Erdos-Renyi and Barabasi-Albert networks types of different sizes ranging from 4,096 nodes to 1,048,576 nodes. We find that utilisation and market behaviour depend on the network type but not the size. Similarly different price update algorithms have little effect on the price development, which is more determined by the network type. We also measure the average buffer size and number of messages in the system. For the Barabasi-Albert network we find that the buffer size of each node has an effect of the price development in the system. The results are useful to guide designers of p2p Grid computing system, like the Global Open Grid.
