Abstract Most applications of Wireless Sensor Networks (WSNs) assume the presence of
single-channel Medium Access Control (MAC) protocols. In the usual dense deployment of
the sensor networks, single-channel MAC protocols may be deficient because of radio
collisions and limited bandwidth. Hence, using multiple channels can significantly improve
the performance of WSN. Recent developments in sensor technology, as seen in
Crossbow's MICAz Mote, Rockwell's WINS nodes and IEEE 802.15. 4 Zigbee, have enabled …

Wireless Sensor Networks (WSNs) are witnessing a momentum spread especially with the
growth of the Internet of Things (IoT) paradigm. Indeed, WSNs are considered as the main
enabling infrastructure for IoT networks. Nowadays, the emerging WSNs applications
require not only long network lifespan but also considerably high data rate. Consequently,
conceiving Multichannel MAC protocols that save the scarce energy budget of sensor nodes
while providing high network throughput is crucial for the emerging WSNs applications. In …
