Indoor wireless communications using slotted non-persistent ISMA, 1-persistent ISMA and non-persistent ISMA/CD

The performance of slotted ISMA protocols has been analyzed in a Rician fading channel for indoor wireless communications considering pico cellular systems. The throughput of slotted nonpersistent inhibit sense multiple access (np-ISMA), slotted 1-persistent ISMA (1p-ISMA) and slotted np-ISMA/CD (collision detection) is investigated in the presence of n-interfering signals. Numerical results are presented, indicating the effect of propagation impairments on the channel capacity. The results are of importance for mobile networks and indoor wireless office communications.
