In this paper, the authors present McMAC, a lightweight, low power and multi-channel MAC protocol for duty cycled Wireless Sensor Networks (WSNs) based on the strobed preamble sampling technique first presented in XMAC. Although many MAC protocols for duty cycled WSNs have been proposed so far, McMAC is the first protocol, to the best of the authors' knowledge, that exploits in a lightweight fashion parallel transmissions over the entire range of IEEE 802.15.4 channels. This results in considerable improvements in terms of energy saving and achievable throughput with respect to preamble sampling based protocols relying on a single channel.
