Now we have designed the simulator, add a new MAC protocol to NS2, and implement the Random Resend MAC protocol, the final part will be analyze the trace file to measure the performance of our new protocol.

Now we have the simulation script, and also added our protocol to the NS2 simulator, which is still a placeholder. Now we're going the actually implement our own random MAC protocol.

In previous post, we wrote an NS2 simulation program that fits the project specification, except that we're using the standard 802.11 MAC protocol. In this post, we'll discuss how to add our own MAC protocol to NS2.

In this network project, we would need to:

• Write an simulator using TCL
• Add an new MAC protocol to NS2
• Analyze the simulation results

Let's tackle them one by one. In this post, we'll mainly focus on the simulator part.
