Consider an N-node ring topology network, as shown in Figure 4.3. Write a computer program to create ring topologies with N ? {20 , 40 , 60 , 80 , 100 }. Now, for each topol- ogy, add LLs based on pure random addition strategy where the addition probability p ? {0.01, 0.05, 0.10, 0.20}. Make your observations based on the degree distribution plots after the addition of LLs.
