While this can be helpful most of the time, around the holidays it could seriously ruin some surprises. Avoid making any Grinch-like moves this holiday and manage your Amazon shopping notifications in the Alexa app to help keep the magic alive.

  While running ns2, we always get the same results as much we run with the same parameters. If we need to get different results for running with same parameters,we need to add some random property in our scripting. By using this property, we can check what goes wrong at an exact point. Normally in ns2, simulations are under three categories; DETERMINISTIC SETTING This setting is the default setting of ns2 and we get the same output in every run. This simulation scenario is usually convenient for debugging process and to locate errors that occurred in simulation codes or to study about complex nature of networks. So while running in deterministic setting, we will get same results on every time and which helps easy to analysis. RANDOM SETTING In case of a statistical analysis, we are forced to simulate a simulation scenario several times and to find out mean & variance. By using deterministic setting we are not able to do this because the variance is zero for that. So we have to...
