Performance Analysis of Periodic Busy Tones Protecting a ZigBee Network from Wi-Fi Interruption

Coexistence and Interference Mitigation for WPANs and WLANs From Traditional Approaches to Deep Learning: A Review

“…The CBT increases the ZigBee throughput in the presence of WLAN co-channel interference. Similarly, Ock et al [65] extended the CBT into a periodical CBT that is effective in mitigating the interference for a multi-hop ZigBee network. Sangsoon et al [66] presented another solution named Narrow Band Protection (NBP), which is also based on the idea of the CBT.…”

“…Yuan in [58] Easy and fast to implement in a distributed manner The channel can be seized by the other nodes if the ED threshold does not decrease promptly Ndih in [59] Simple and efficient in mitigating the interference Need to modify the IEEE 802.15.4 and firmware Wang in [56] Easy and simple to implement The MAC delay increases due to RSSI readings Chen in [68] Simple to implement with the increased ZigBee throughput Decrease in WLAN throughput by 10% [16], [65] Effectively protect ZigBee from the WLAN interference The busy tone might consume high energy and the interactive process could increase the delay Hong in [60] Simple and efficient in mitigating interference Need a controller and increase energy consumption If the controller fails, the system breaks down Sangsoon in [66] Easy and simple to implement ZigBee consumes more energy…”

Joint Channel Allocation and Routing for ZigBee/Wi-Fi Coexistent Networks

“…This makes it easy for Wi-Fi STAs and APs to detect ZigBee signals. Similar approaches with signaler are introduced in [19] and mathematically analyzed in [20]. Queue-size based Busy Tone (QBT) [21] applies the approach with signaler to multi-hop ZigBee network, and implements it on n embedded platform.…”

Busy tone based coexistence algorithm for WRAN and WLAN systems in TV white space

“…Due to the nature of these two networks, only indoor channel model is considered and shadowing effect is disregarded. Also in [25], similar BT-based algorithm and its analysis is studied among IEEE 802.11 and 802.15.4 networks, but only IEEE 802.11 devices are considered as the interference sources since an IEEE 802.15.4 device, i.e. ZigBee node, has much lower transmit power level than IEEE 802.11 Wi-Fi devices.…”
