In cooperative work like online games, a mediation host mediates differences of delay and the consistency of the data shared among the participating hosts (total orderings). When such applications are used on mobile ad hoc networks, one of the network hosts must take this role. If the mediation host is near the center of the network, the communication delay and traffic load are smaller, and the efficiency of application programs is better. However, the hosts move around, so the network topology changes, so meaning that the mediation host may be located far from the center. We previously proposed a method for reassigning the mediation function as the topology changes so that a host near the center plays the mediation role.We have now evaluated the performance of our method from the view points of communication delay and the number of host reassignments on ad hoc networks by simulations, using DSR dynamic source routing as the routing protocol.
