Adaptive Quality Of Service Multi-hop Routing
In multi-hop networks, Adaptive Quality of Service routing (AQoS or AQR) protocols have become increasingly popular and have numerous applications. One application in which it may be useful is in Mobile ad hoc networking (MANET).
Adaptive QoS routing is a cross-layer optimization adaptive routing mechanism. The cross-layer mechanism provides up-to-date local QoS information for the adaptive routing algorithm, by considering the impacts of node mobility and lower-layer link performance. The multiple QoS requirements are satisfied by adaptively using forward error correction and multipath routing mechanisms, based on the current network status. The complete routing mechanism includes three parts: (1) a modified dynamic source routing algorithm that handles route discovery and the collection of QoS related parameters; (2) a local statistical computation and link monitoring function located in each node; and (3) an integrated decision-making system to calculate the number of routing paths, coding parity length, and traffic distribution rates.
The adaptive cooperation concept has future promises to overcome infrastructure loaded approaches and to get rid of central facilities with autonomous networks in industrial and home applications.
The United States Air Force is determining the best way to employ QoS protocols into Airborne Networking. Research composed shows that Adaptive QoS that uses cross-layer cooperation has provided the best results for military applications.

Famous quotes containing the words adaptive, quality and/or service:
“The shift from the perception of the child as innocent to the perception of the child as competent has greatly increased the demands on contemporary children for maturity, for participating in competitive sports, for early academic achievement, and for protecting themselves against adults who might do them harm. While children might be able to cope with any one of those demands taken singly, taken together they often exceed children’s adaptive capacity.”
—David Elkind (20th century)
“It is not stressful circumstances, as such, that do harm to children. Rather, it is the quality of their interpersonal relationships and their transactions with the wider social and material environment that lead to behavioral, emotional, and physical health problems. If stress matters, it is in terms of how it influences the relationships that are important to the child.”
—Felton Earls (20th century)
“Human life consists in mutual service. No grief, pain, misfortune, or “broken heart,” is excuse for cutting off one’s life while any power of service remains. But when all usefulness is over, when one is assured of an unavoidable and imminent death, it is the simplest of human rights to choose a quick and easy death in place of a slow and horrible one.”
—Charlotte Perkins Gilman (1860–1935)
