Abstract :
Variable environments in ad hoc networks require a joint control of physical (PHY) and medium access control (MAC) layers resources in order to optimize performance. In this paper, we propose a framework to perform such cross-layer control and optimization. The PHY layer and cross-layer engine estimate and predict the channel variations to evaluate the linkpsilas future packet error rate (PER), for MAC layer optimization. We consider high capacity code division multiple access (CDMA) ad hoc networks where nodes are equipped with matched filter receivers.
