    abstract     = {Summary: To locate surrogate servers on optimal positions in hybrid P2P networks, in this paper, a locating of super nodes (or surrogate servers) by considering user activities is proposed.Active nodes are grouped by clustering algorithms and locations of super nodes are presented as centroids of clusters to increase a quality of service (QoS) and provide fast response to users, which can be applied in video distribution systems such as video-on-demand services. To evaluate our work, it is simulated on a grid overlay network with different number of both super nodes and active nodes. The simulation result shows that the communication time (response time) for accessing content is minimised and it is also related to the number of super nodes.},
