“…Such works can be classified into three main categories: split-connection schemes [2], localized link layer solution [3], and end-to-end schemes [4]. Among them, strictly end-to-end schemes at the transport layer have been paid much attention because they require no support from the network.…”

In this paper, we propose an improved TCP scheme, TCP BRJ, which is capable of adjusting the initial slow-start threshold and congestion window in real time according to the bandwidth estimation in slow-start phase, dividing the network congestion grades based on round-trip time (RTT) jitter in congestion avoidance phase, distinguishing the random packet losses from the congestion packet losses, and reacting accordingly. Simulation results by NS-2 show that TCP BRJ provides more significant performance improvement in throughput, bandwidth utilization and fairness than TCP Reno and TCP Westwood in heterogeneous networks with high random bit-error rate (BER), and shows friendliness towards the widely used algorithm TCP Reno.

“…As an end-to-end scheme [2,3,4], TCP Veno [5] can provide a significant improvement in the wireless networks and show friendliness towards TCP Reno in simulation and Internet measurements. It estimates the number of packets (N) backlogged in the router buffer and compares N with a fixed threshold β (generally 3) to differentiate the random packet losses from network congestion and adjusts the cwnd accordingly.…”

In the past decades, many end-to-end TCP enhancements have been presented for the wireless networks with high bit-error rates (BER). As a typical example, TCP Veno mainly enhanced the performance suffering in the wireless networks. However, the fixed queue length threshold and traditional fast recovery algorithm make TCP Veno unable to adapt to the network states changes. In this paper, we propose an enhancement based on TCP Veno, called TCP VenoDR, which has two improvements: differentiating the random loss from congestion loss based on an adaptive queue length threshold of bottleneck link, and a dynamic recovery algorithm (DR) in the recovery period by adopting a dynamically adjusted variable to control the congestion window (cwnd). The simulation results by NS-2 show that VenoDR obtains a significant performance in throughput, bandwidth utilization and fairness over the traditional TCPs, such as Veno, Westwood, and Reno in wired/wireless networks.

In this paper, a novel mutation operator of differential evolution algorithm is proposed. A new algorithm called divergence differential evolution algorithm (DDEA) is developed by combining the new mutation operator with divergence operator and assimilation operator (divergence operator divides population, and, assimilation operator combines population), which can detect multiple solutions and robustness in noisy environment. The new algorithm is applied to optimize Michalewicz Function and to track changing of rain-induced-attenuation process. The results based on DDEA are compared with those based on Differential Evolution Algorithm (DEA). It shows that DDEA algorithm gets better results than DEA does in the same premise. The new algorithm is significant for optimizing and tracking the characteristics of MIMO (Multiple Input Multiple Output) channel at millimeter waves.
