The goal of this effort is the design and implementation of QoS network provisioning strategies that (1) permit real time delivery of QoS services by promptly accepting new calls, and (2) enable prompt recovery (within 100-300 ms) from QoS interruption dueto use/network mobility or network failures.… More

The exploding demand for computing and communication on the move has led to a significant need for ad hoc networks. However, there is relatively little understanding of the behavior of such networks, as they are scaled up, particularly for traffic withstrict Quality of Service requirements. The… More
