| Abstract(in English) | The number of supportable VoIP sessions is small in wireless multi-hop networks using IEEE802.11 due to the overhead of CSMA/CA. In this paper, we propose a method to ensure VoIP quality and to increase the number of supportable VoIP sessions by controlling the amount of traffic adaptively with a combination of VoIP silence suppression and traffic monitoring in routers. In the proposed method, routers detect congestion by monitoring the time required to transmit a packet. When congestion is detected silence suppression control and admission control are applied. We show results which demonstrate that the number of supportable sessions can be increased by 240% compared with the case when silence suppression is not used. |
