Paper Title:
Quality Estimation of Bandwidth in a Network
  Abstract

The available bandwidth (avail-bw) in a network path is of major importance in congestion control, streaming applications, quality-of-service verification, server selection, and overlay networks. In a packet network, the terms bandwidth and throughput often characterize the amount of data that the network can transfer per unit of time. Bandwidth estimation are also important for traffic engineering and capacity planning support. We propose a QoS-aware routing protocol that incorporates an admission control scheme and a feedback scheme to meet the QoS requirements of real-time applications. Results of our experiments show that the packet delivery ratio increases, and packet delay and energy dissipation decrease significantly, while the overall end-to-end throughput is not impacted, compared with routing protocols that do no provide QoS support. Nevertheless, the load is better balanced in the network, therefore the network capacity is not overloaded. The result in more stable routes and less control traffic as almost no reconstructions are needed.
