Dynamic Neighbour Aware Power-controlled MAC for Multi-hop Ad-hoc networks

A Hidden Node Aware Network Allocation Vector Management System for Multi-hop Wireless Ad hoc Networks

Many performance evaluations for IEEE 802.11distributed coordination function (DCF) have been previouslyreported in the literature. Some of them have clearly indicatedthat 802.11 MAC protocol has poor performance in multi-hopwireless ad hoc networks due to exposed and hidden nodeproblems. Although RTS/CTS transmission scheme mitigatesthese phenomena, it has not been successful in thoroughlyomit...

Optimal Power Control MAC for Multi-hop Cognitive Radio Ad-hoc Networks

This paper presents a novel MAC protocol that allows the secondary links to optimally adjust their transmission power and persistence probability on an ingress rate basis regulated by cognitive users (CUs) for multi-hop cognitive radio ad hoc networks (CRAHNs). By introducing a unique collision probability constraint required by spectrum holder, we show that the CUs can opportunistically access...
