| Abstract(in English) | Many studies proposed a rendezvous search method that multiple searchers starting from different nodes on a network try to meet at the same node. Among the methods, rendezvous search methods on unknown networks, where each node can only obtain the information of its adjacent nodes, is expected for utilizing various networks, such as mobile ad-hoc network and social network. We has proposed a rendezvous search method (a random walk search method) using random walks in order to reduce the load of a flooding search method, which can perform the fastest rendezvous search on unknown networks. Although the random walk search method will be used in large-scale networks, we do not clarify its effectiveness. In this paper, we evaluate the effectiveness of the random walk search method in large-scale networks, by the comparison with the flooding search method. According to the results, we show the high effectiveness of the random walk search in large-scale scale-free networks. Especially, in the networks with 10, 000 nodes, the random walk search can finish as fast as the flooding search with while its load is 0.2% lower than that of the flooding search. |
