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.
