Inter-cell interference in CSMA-CA wireless networks for different bandwidth divisions

We study interference impairment in a multiaccess point (multiAP) wireless network, where available bandwidth is divided to N_s channels. The medium access control (MAC) protocol of the network is carrier sense multiple access with collision avoidance (CSMA-CA). We investigate the effect of inter-cell interference (ICI) on the throughput of the network for different values of N_s. ICI reduces the duration of time the node has access of the medium and increases the probability of retransmission. We simulate a CSMA-CA network in indoor environment and find outage probability and spectral efficiency for different values of N_s.
