Topology adaptation based on mobile agent in unstructured P2P networks

Abstract

Peer-to-Peer (P2P) network has shown encouraging capacity in facilitating multimedia communication over Internet. This paper focuses on the topology adaptation in P2P networks. A new topology adaptation approach based on mobile agent is proposed to resolve the congestion caused by resource location in unstructured P2P networks. In our approach, peers direct mobile agent to migrate to the potential congestion peers based on their neighbors' characteristics including processing capacity and connectedness. Thus congestion can be found effectively and the topology optimization mechanism is then used to resolve the congestions. Simulation results show that the proposed method can improve networks topology, avoid congestions effectively and increase the efficiency of resource location. © 2012 Springer-Verlag.
