| Abstract(in English) | In wireless mesh networks using CSMA/CA, existence of multiple on-going flows in the same frequency can degrade total bandwidth utilization efficiency due to mutual interference, particularly in the case that each flow is located in the interference range of other flows. To overcome this problem, we have proposed an approach of adaptively controlling channel reservation area by RTS/CTS depending on the interference range between multiple flows, and demonstrated its effectiveness in an equal-distance node placement model. In this paper, we present an extension of our scheme to be applied to networks with more general node placement. Results of performance evaluation by simuation show that the proposed scheme improves bandwidth utilization efficiency by approximately 10% over existing CSMA/CA with RTS/CTS, especially in the network with active flows whose number is up to 5. |
