An Iterative Algorithm for Optimal Carrier Sensing Threshold in Random CSMA/CA Wireless Networks

We investigate the optimal carrier sensing threshold in random CSMA/CA networks considering the effect of binary exponential backoff. We propose an iterative algorithm for optimizing the carrier sensing threshold and hence maximizing the area spectral efficiency. We verify that simulations are consistent with our analytical results.
