Abstract
A method and apparatus for optimizing a cross layer in an ad-hoc wireless network are provided. A link price is set using the number of packets of a queue. A flow rate is set using the link price. A channel access rank is set by comparing the link price with a link price of a neighboring node. A channel access backoff time is set based on the channel access rank. The method and apparatus for optimization may not be subject to interference and can simultaneously obtain fairness and efficiency while adaptively setting link capacities.
