Fair bandwidth allocation and congestion control is an important issue when accessing a common shared link in the modern TCP/IP networks. In this paper, we propose and evaluate fair downlink bandwidth distribution method which is based on online upstream control and limitation. The method is designed to maintain the fair shared bandwidth allocation by adaptively controlling the upload rate of the...
According to the features of high dimensional, nonlinear and redundant of the Credit Scoring data, the establishment of a model for credit scoring has a direct bearing on the complexity of personal credit scoring process and the collection of characteristic parameters reflecting the credit scoring status constitutes an important link for setting up a efficient model, to resolve the problem that it...
We develop a new experimental system for secure communication with nonlinear mixing of information signal and chaotic signal of a time-delay system. The proposed scheme is based on programmable microcontrollers with digital transmission line. The scheme allows one to transmit and receive speech and musical signals in a real time without noticeable distortion.
In this paper, a cascaded-clear channel assessment (CCA) which combines the advantage of energy detector (ED) and matched filter (MF) is proposed, namely CEM: Cascaded Energy detector Matched filter. CEM incorporates energy efficiency of EDand the reliability of MF. The probability of detection and false alarm of ED, PD and CEM are depicted in receiver operation curves (ROCs) of proposed scheme that...
