Hey I couldn't run http://www.inf.ufrgs.br/~wlccordeiro/resources/olsr/README.html shell script provided here the scripts run.sh and result.sh are actually a batch for processing the wtrace.tr file generated during the simulation execution. run.sh runs the simulation 10 times, using 10 different seeds for the random number generator, and result.sh aggregates the information about throughput, delay, jitter, and packet loss from all the 10 simulations, and outputs a .txt that contains data to plot graphics for each of these aspects evaluated. but these script won't run why ?
