An overlay approach to data security in ad-hoc networks
While it has been argued that application-layer overlay protocols can enhance services in mobile ad-hoc networks, hardly any empirical data is available on the throughput and dela...

Improving Throughput and Fairness by Reducing Exposed and Hidden Nodes in 802.11 Networks
Abstract--Two well-known problems that can cause performance degradations in IEEE 802.11 wireless networks are the exposednode (EN) and hidden-node (HN) problems. Although there ha...
