Such a distributed bandwidth broker has been implemented and tested in NS simulator. Its operation is affected very much by the network condition and the responding time is proportional to the delay of packets in the network. Therefore, the paper presents a model (heuristic) that evaluates each node and finally selects the most important node where the base bandwidth broker should be located. This model is also associated with the general model that describes the operation of the bandwidth broker, and we propose an adaptation module of the Bandwidth broker that optimizes its operation. Finally, the model is simulated in order to evaluate its performance and indicate points that can be improved.1 aBouras, Christos1 aPrimpas, Dimitris  uhttp://telematics.upatras.gr/telematics/publications/host-selection-model-distributed-bandwidth-broker?language=en
