Topology adaptive approach based on mobile agent in unstructured P2P networks
基于移动agent的无结构P2P网络拓扑重连方法研究

To enhance the efficiency of resource location and avoid congestion in unstructured P2P peer to peer networks, this paper proposed a mobile agent based topology adaptation approach. Peers in the network launched reconnection mechanism periodically, and collected their neighbor peers' information such as processing capacity and connectedness to direct mobile agent to migrate in the network on purpose. Thus mobile agent could find congestions in peers effectively and used the topology optimization mechanism to decrease the query loads in those peers. Experimental results show that the algorithm can improve networks topology structure, avoid congestions, increase the efficiency of resource location, and adapt to the dynamic change of query loads.
