Multimedia centric P2P must take into consideration the main characteristics and the complex relationships among multimedia objects. In this paper, we propose a clusterbased Hybrid Overlay Network HON-P2P for sharing multimedia content. It consists in clustering peers with similar feature based or semantic properties. We define two types of clustering methods corresponding to the semantic and feature based overlays: semantic clustering and feature based clustering. To improve the information retrieval in the HON-P2P network we propose a multimedia cache management methodology. Semantic multimedia cache and feature based multimedia cache are defined for each type of overlay. Moreover, we study the cache placement possibilities inside the cluster and we propose a cache distribution technique taking into account peers capabilities and range query
