The Paper which I chose as my base paper for my final year project is "Self-sustaining, efficient and forward-secure cryptographic constructions for Unattended Wireless Sensor Networks". It is told that i should implement with NESc and tiny OS, opnet tools for implementation. But i'm well versed with NS2 and Opnet Alone. can i make my implementation using these tools and if someone has tried this topic before, pls suggest me an idea.
