6. Work done so far Understood the IBMA Protocol
Qualnet directory structure and its implementation of various protocols
Learnt the Qualnet Simulator
Made scheme to implement IBMA protocol in Qualnet

7. Work to be done Implement the IBMA protocol in Qualnet
Modify the existing protocol of Qualnet which is not having power control
Add adaptive power control in that protocol.
Compare the simulation results
