Adaptive QoS Performance
Three functions (routing function, local statistic computation and monitoring function, and integrated decisionmaking function) are implemented in the different parts of the mobile network. Due to the distributed structure, the computation and implementation complexity of the routing scheme are reduced. Also, since routes are discovered based on the up-to-date local information and selected by the optimization computation, routing parameters (e.g., number of paths, FEC parity length, and traffic distribution rate) are dynamic and optimized. In addition to supporting multiple QoS requirements, traffic balancing and bandwidth resources are factored into our decisionmaking process. The distributed structure of the local QoS statistics used in the routing enables this QoS support mechanism to be scalable in mobile networks. Simulation results indicate that the performance (i.e., packet loss and end-to-end delay) are much better and less susceptible to the state changes (i.e., node mobility, transmission power, channel characteristics, and the traffic pattern) of the network, compared to a nonadaptive routing strategy.

Famous quotes containing the words adaptive and/or performance:
“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)
“The honor my country shall never be stained by an apology from me for the statement of truth and the performance of duty; nor can I give any explanation of my official acts except such as is due to integrity and justice and consistent with the principles on which our institutions have been framed.”
—Andrew Jackson (1767–1845)
