This paper presents a new method to estimate the available bandwidth and the path capacity over a wireless network path, denoted as rt-Winf. The estimation is performed in real-time and without the need to intrusively inject packets in the network. This is accomplished by resorting to the CSMA-CA scheme with RTS/CTS packets to determine each node's channel allocation. rt-Winf repeatedly samples the...
In the general wireless network, the network terminal often cannot dynamically select the best path to access the network due to the absence of the detailed network parameters, which may cause the performance reduction of the network. In this paper we propose a new dynamic access link selection scheme (DALSS) based on the real time network state. The estimation of capacity and available bandwidth...
In this paper, we propose a novel fuzzy logic congestion control mechanism to improve throughput performance of transmission control protocol (TCP) in wireless high-bandwidth delay networks. It is based on a receiver centric method of which the available bandwidth is measured at the receiver. The available bandwidth utilization serves as an incipient network congestion indicator, which acts as one...
The motivation for our work was a feasibility study of the use of wireless technologies, more concretely IEEE 802.11, in industrial control systems. The considered application for configuration files upload to a system component puts requirements on the throughput of the established connection. To estimate the TCP throughput under the large range of varying conditions an analytical model has been...
