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