“…Unlike the existing works such as Refs. [14][15][16][17][18][19] (discussed broadly in the related work section) where the system evaluations are performed either in simulated environments or in impractical environments, as well as in scenarios that lack considering some actual real network attributes, such as interference from other networks and continuous transmission from an interference source, that are very common in real world, our paper provides experimental results obtained from a real hardware-based experimental testbed located in an indoor environment. e main contributions of the paper relate to the performance analysis of a Zigbee network in the presence of a Wi-Fi interference network.…”

Zigbee is a very popular technology for Internet of things (IoT) networks mainly because of its low power consumption and low-cost features. It shares the unlicensed 2.4 GHz Industrial, Scientific, and Medical (ISM) radio band with other wireless networks such as Wi-Fi. Usually, Zigbee and Wi-Fi networks coexist in indoor environments for their respective applications. Hence, the coexistence introduces interference for both types of networks lowering the performance of the networks, but Zigbee suffers more significant performance losses because of its lower transmission power than Wi-Fi. Since the number of IoT devices is increasing at an unprecedented rate due to numerous emerging applications and thus making the indoor environments very populous, the peaceful coexistence between Zigbee and Wi-Fi networks in proximity becomes an important research study. For this purpose, this paper presents a comprehensive performance study of a Zigbee network in the presence of a Wi-Fi interference network in a real-life apartment-based indoor environment where Wi-Fi access points of dense neighbors exist. The experiments were done in a XBee module-based Zigbee network for measuring the received signal strength indicator (RSSI), packet drop rate (PDR), and loopback throughput with and without nearby Wi-Fi traffic introduced on purpose. Various networking parameters such as the operating channels, the distances between Zigbee devices and Wi-Fi devices, the transmit timeout of Zigbee packets, and the transmission power of the Zigbee transmitter have been used in the experiments to study the network performance. Our results show that in the deployment of IoT networks in a smart home, radio interference from neighboring homes would not be an important factor, but serious considerations may need to be taken inside the same home. The experimental observations of this paper can serve as a good reference study for Zigbee network deployments in real indoor environments, particularly when interference sources are present in proximity.

“…Because of this, the two technologies usually operate in proximity and they have to co-exist together. However, WiFi consumes higher power level, while ZigBee uses low power [10].…”

“…Because of this interference, a decrease in the performance of the wireless networks is noted. Wi-Fi and ZigBee are expected to run simultaneously in close proximity due to the demand for ubiquitous Internet access and increasingly, these two networks are being utilized in urban areas to support real-time and long-term monitoring [10]. Interests in using these two networks to coexist in different systems have intensified and one of these systems is in smart homes.…”

The possibility for the home to be networked wirelessly has greatly improved because of emerging technologies. Home networking is very much possible now with the different technologies that are available. This project is an application of two wireless technologies to machine-to-machine (M2M) home networking coexisting together. The networking technologies used and evaluated in the project are ZigBee and Wi-Fi, where the risk of interference in the networks is identified and evaluated. The M2M home network system that was developed and implemented is an interconnection of electronic home devices grouped by sub-networks categorized by each of the wireless technologies. Because the two sub networks are working in proximity, there is t high chance of interference. Connection for Zigbee include home electronic devices such as light fixtures, television, stereo, etc., and Wi-Fi's network is connections of remotely monitored IP cameras. The joint application of the two networks showed how these networks affect each other and how they coexist in one system. The paper explored the risk of interference of these two systems when the system is implemented. Guidelines were developed to overcome and mitigate these constraints.

This paper presents an in-depth analysis on the effect of the coexistence in the 2.4 GHz band between IEEE 802.15.4 and IEEE 802.11 on the medium access control. We focus on the slotted CSMA/CA medium access algorithm that is used by IEEE 802.15.4 and we analyse the delay that frames undergo when suffering from interference from a WiFi activity. We measure the overhead caused by the additional delay spent in the MAC sublayer frame queue before accessing the medium due to the presence of WiFi interference. We experimented different scenarios with overlapping channels and non-overlapping channels. We show that the two wireless protocols can coexist if we take into considerations the relative positions of the nodes to avoid very high interference and if we avoid monopolizing the channel with a very high rate WiFi traffic even under overlapping channels.
