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.
