In order to solve the frame overhead to the influence of frame transmission performance, improve the throughput, lower hybrid scenario user acces delay, improve user (802.11 n) especially the user experience, this paper aimed at different rate of terminal equipment, designs the RAS algorithm, this algorithm through optimizing scheduling, in does not affect user delay at low speed, reduce the hi...

Real-time multimedia applications prefer smooth and predictable throughput to TCP-like abrupt sending rate changes, and this led to the development of TCP-Friendly Rate-based Congestion Control (TFRC). However, we observed a longterm throughput imbalance between TFRC and TCP sources, especially under a low level of statistical multiplexing. We set out to reduce these differences by re-introduci...

Experimental studies have shown that traditional rate adaptation schemes for 802.11 wireless networks suffer from significant throughput degradation in highly congested networks. To address this problem, this papermakes the following twomain contributions. First, we design a method to accurately estimate the per-packet transmission times, and we use these measurements to provide a broad classif...

In this paper, to realize the low delay and high throughput route discovery in multi-rate ad hoc networks, we propose a novel ondemand routing using signal strength, called signal strength aware routing (SSR). SSR is based on the on-demand routing with the route request (RREQ) and route reply (RREP) procedure. In SSR, a node measures the signal strength of a received RREQ, and calculate the app...

One of the hot issues in heterogeneous wireless networks (HWNs) is radio resource utilization. The objective of this paper is to solve this problem. By considering the diversity of radio access technologies (RATs) in HWNs, the differences between them should be studied and exploited, e.g., coverage radius of each network, service arrival rate of each region, data transmission rate. The paper pr...

conclusions by applying wes, both novel and known scz pathogenic variants with complete or incomplete segregation in the families with multiple cases of schizophrenic patients were identified. background schizophrenia (scz) is a complex neuropsychiatric disorder characterized by pronounced genetic heterogeneity. much of the genetic architecture of the disorder has not yet been clearly elucidate...

resource allocation techniques have recently appeared as a widely recognized feature in lte networks. most of existing approaches in resource allocation focus on maximizing network’s utility functions. the great potential of utility function in improving resource allocation and enhancing fairness and mean opinion score (mos) indexes has attracted large efforts over the last few years. in this p...
