Network Performance Evaluation - Science topic

Hello,

In my experiment setup, I have different servers that host files with different sizes. The client downloads files continually and estimates the performance of each server by estimating the throughput. However, when I download a big file it shows higher throughput comparing small files.

My question, for a given server, how I can aggregate correctly the measured throughputs to have a single value that represents its performance.

Thank you very much for your time.

dear all, i'm a newbie in ns2, and i got assigment to implement OLSR + PGB in ns2, my problem is i don't know how to get signal strength neighboar. i need "signal strength" to split into 3 area (in, PGB, out) then i can chose MPR in PGB area only. can you help me sir, please regrad

Hi all, 

Currently, I am doing a research in classifying RBCs into four groups.

After extracting best features, I trained a pattern recognition Neural Network and performance is evaluated by 10-fold cross validation check. Miss-classification rate is around 6%. 

In another experiment, I tried to use SVM model to classify one group and three other groups so called one-versus-rest classifiers. Then again repeated same strategy for the 3-group class until there is no need for another binary classification. Performance is evaluated by the same technique applied in the Neural Network strategy. Miss-classification rate for the first binary SVM classifier is zero and for the second and third binary SVM classifier is 2.1% and 3.2%. Which strategy is better and why?

If multi stage SVM is outperforming NN strategy, how can I evaluate the miss-classification rate?

Cheers,

what are the latest trends in the queuing network optimization

In my setup, the probability density function of the noise is not Gaussian-like and its PDF changes with the system statement.

Thus, I want to use the BER calculation by error counting instead of BER estimation. Moreover, the experimental BER level is around 10^-5. However, it seems the common method to calculate the BER is based on the PDF estimation.

How can I calculate the error by direct error counting? I set up a simple system model in the attachment.

Could anyone give me some advice?

I am searching for the best network simulator to evaluate the performance of safety application through WSMP protocol in vehicular ad-hoc networks. I could only find NCTUns 6.0. I'm just wondering if there are other means to do the evaluation or other types of network simulator?
