3. The Difference Parts in MAC Layer
The Non-persist CSMA/CA algorithm is promoted to instead of CSMA/CA in IEEE
The Distributed Contention Access Scheme is promoted to improve the CAP optimization

5. Conclusion
The proposed non-persistent CSMA mechanism based on the new CAP channel model reasonably reduces the complexity of CCA analysis, and improves the accuracy of throughput by considering the influence of timeout period.
Based on the features of WPAN and proposed np-CSMA, a CAP optimization scheme is derived to obtain the optimal throughput.
