Knowing link characteristics of a network connection is essential for the efficient design, management, and usage of a network. In view of the proliferation of power line communication systems, in this work, we propose a novel measurement approach, called PLC-Probe, to concurrently measure link capacity and available bandwidth of PLC links. PLC-Probe uses ‘train-chirps’ to probe the network, and it...
A distributed approach to perform admission control in multi-hop ad hoc networks is proposed. Existing algorithms normally compute the total amount of available resources in the network, however our method evaluates if there are sufficient resources to satisfy the bandwidth demand of a new incoming flow rather than quantifying the total amount, which is impractical when considering implementation...
In this paper, we propose a practical, efficient and real-time technique to estimate the end-to-end available bandwidth in the condition of probe packets losing. One of main ideas of the proposed technology is compensation mechanism, which uses a least square method to approximately compensate the losing packets based on polynomial-mimesis technology in the communication channel. The second is that...
