As Grid systems distribute geographically, they become more heterogeneous and dynamic in terms of resources. Discovery service is an important issue in grid systems. Grid efficiently is as regards resource discovery in scalable and dynamic environments. In this paper, we review the peer-to-peer (P۲P) based decentralized discovery methods: Unstructured and Super-Peer. We describe major development of these approaches and provide discussion concerning efficiently and scalability features.
