So how to improve wireless data transmission rate and the network throughput,reduce transmission delay, and finally keep the superiority of CDMA 1X network′s higer wireless data transmission rate, is a key project of the CDMA Network Optimization Center.
When AH or ESP protocol is applied to data packet of IP, the increase of the length of data packet will cause the increase of network load and transfer delay. This article introduced the application of IPComp in IPSec in order to solve this problem.
Assuming that the transfer delay is so small that it can be ignored, the networked control system based on multiple-packet transmission is an asynchronous dynamical system with N events, which incorporates continuous and discrete dynamics.
Simulation results demonstrate that 2-approximation heuristic (1) performs close to the optimal scheduling, and (2) outperforms ADJUST and DOUBLE in terms of traffic transmission delay and time complexity.
Compared with IEEE 802.11 Distributed Coordination Function (DCF) protocol, the results show that the proposed mechanism improves the average throughput and limits the transmission delay efficiently.
Simulation results demonstrate that higher goodput, lower packet loss rate (PLR), lower frame transmission delay and jitter with good fairness can be achieved by our proposed mechanism.
Transmission delay based control over networks with wireless links
Then present a strategy using information feedback by the last hop acknowledgement and monitoring the queuing level of the wired bottleneck link by calculating the changes in transmission delay along the path.
We employ a discrete-time analysis of the queueing network model to obtain the packet-level performance measures, such as the end-to-end packet transfer delay, the packet loss probability, and the throughput.
In numerical examples, we show some packet transfer delay distributions and effects of the packet size on the packet loss probability.
First, to ensure graceful picture quality degradation by minimizing the cell loss probability for critical video data while guaranteeing a bounded cell transfer delay.
The impact of the "time-out" phenomenon on the network performance and especially the improvement of the transmission efficiency and the average packet transfer delay by using the proposed scheme are shown.
The simulation results show that the end-to-end cell transfer delay and cell loss of each source has been improved significantly.
This is because the latency is dominated by the protocol software execution time in the kernel, instead of by the raw transmission time over the link.
It was assumed that the distribution functions of packet transmission time, inter-error duration, and time of elimination of the disturbing factor are arbitrary as well.
This paper is concerned with the transmission time of an incident Gaussian wave packet through a symmetric rectangular barrier.
The synchronous neuronal firings are detected at each peak of the beating, regardless of difference in signal transmission time between SI-to-CS and SII-to-CS pathways.
Theoretical analysis and experimental results show that the ratio between the lightest weight display time and the relative transmission time is a tradeoff between brightness loss and transmission efficiency.
