In this paper, the effect of co-channeled BlueTooth (BT) piconets on a Carrier Sense Multiple Access (CSMA)-based Wireless Local Area Network (WLAN) is investigated. Specifically, the p-persistent CSMA protocol is considered for WLAN and the probability of error of a WLAN packet is calculated in the presence of interfering BT packets of different lengths, variable piconet traffic loads, and as a function of the BT's frequency hopping guard time. The probability derivation is then used in conjunction with the p-persistent CSMA throughput and delay formulations to examine its net performance in the presence of BT interference.
