Abstract:	This paper presents a simple resource control mechanism with traffic scheduling for 2-hop ad-hoc networks, in which the Request-To-Send (RTS) packet is utilized to deliver feedback information. With this feedback information, the Transmission Opportunity (TXOP) limit of the sources can be controlled to balance the traffic. Furthermore, a bottleneck transmission scheduling scheme is introduced to provide fairness between local and forwarding flows. The proposed mechanism is modeled and evaluated using the well-known 20-sim dynamic system simulator. Experimental results show that a fairer and more efficient bandwidth utilization can be achieved than without the feedback mechanism. The use of the structured and formalized control-theoretical modeling framework has as advantage that results can be obtained in a fast and efficient way.
