This paper compares the performance of IEEE 802.11 (Wi-Fi) and IEEE 802.15.4 (Zigbee) networks operating in the 2.4 GHz ISM band, evaluating metrics such as jitter, end-to-end delay, and throughput under different node placements and traffic loads. The findings indicate that the 802.11 network consistently demonstrates lower jitter and delay alongside higher throughput compared to the Zigbee network, particularly in both static and mobility models. The authors suggest that future work may explore collision detection in heterogeneous network placements.
