Peer-to-peer (P2P) systems have grown significantly in recent years due to the ability to share multiple resources. Using the super-peer nodes in peer-to-peer networks has increased the efficiency of these networks. The main problem in these systems is the selection of high-capacity nodes as the super-peer node to join other nodes. The optimal choice is dependant on various parameters such as heterogeneous capacity and dynamic nature of the network. Given the predominant position of the super-peer nodes in the network, the selection of the top node requires a protocol that is aware of the capacity of the nodes. In this paper, we present a method for selecting a super-peer node based on the SG-2 model utilizing the broadcast-service and distance-delay-based Gossip protocol, and use the status messages between neighboring nodes, and search messages to select the most powerful node. Using this method, the efficiency of peer-to-peer networks will increase and the time of convergence to the optimal overlay network will be reduced.

While the Grid systems are distributing geographically, the heterogeneity and dynamic features of their resources are increasing. One of the important issues in this systems is adaptation the discovery services with more scalable and dynamic environments to improve the discovery performance. In this paper, we concentrate on the Decentralized mechanisms based on the Peer-to-Peer (P2P) networks and classify the discovery approaches into two main categories: the Unstructured and Super-Peer models. We review the major development of these categories and provide discussion about the efficiency, scalability, and dynamic terms.
