AWK Scripts are very good in processing the data from the log (trace files) which we get from NS2. If you want to process the trace file manually, here is the detailHere is a sample of trace file from NS2 (However ns2 supports a new type of trace file also), but this post will make you understand the old trace format only.r 0.030085562 _0_ MAC --- 0 message 32 [0 ffffffff 1 800] ------- [1:255 -1:255 32 0] r 0.030110562 _0_ RTR --- 0 message 32 [0 ffffffff 1 800] ------- [1:255 -1:255 32 0] s 1.119926192 _0_ RTR --- 1 message 32 [0 0 0 0] ------- [0:255 -1:255 32 0] AWK Scripts are very good in processing the data column wise. For example the first column in the above trace file represents r, s which indicates receive, sent respectively. If we want to trace the entire r and s alone from this trace file we can represent it as $1 So $1 represents ACTION $2 Time $3 Node ID $4 Layer $5 Flags $6 seqno $7 type $8 Size $14 Energy (if the network nodes includes EnergyModel)To run the awk script in Li…
Unlike earlier version of ubuntu, the 18,04 version does not support the direct installation of ns2, because of the latest C/C++ compiler (7.x), but the latest C/C++ compiler supported by ns2 is gcc-4.8. So this post and video tells you about the installation of gcc-4.8 version, then ns2 and then configuration.
Here are the steps, Please follow the video given below for more information.
$] tar zxvf ns-allinone-2.35.tar.gz
$] sudo apt install gcc-4.8 g++-4.8
if you have installed ubuntu just now, you can try these commands also in the beginning
