| Abstract(in English) | Selfish routing is a selfish route selection of players in computer networks. Players are assumed to select paths so as to minimize their data transfer latencies. Recently, selfish routing is analyzed as an evolutionary game. Additional edges are expected to reduce the average latency of data transfers, but such edges may increase the average latency in some single-source single-sink networks. Such a situation is well known as Braess's paradox. In this paper, we formulate multipopulation replicator dynamics of selfish routing in multisource single-sink networks. Then, in a two-source network, we find flows which correspond to stable equilibrium points of the replicator dynamics. We extend Braess's paradox to multisource single-sink networks and show that such a paradox occurs in a network which is added an edge to the two-source network. |
