“…Since more and more wireless devices are equipped to provide multichannel support, parallel data transmission becomes available. Multichannel technology has been demonstrated to significantly increase network capacity, reduce chances of contention and collision of data transmission (Cao Zhiyan and Mingzeng, 2008). Due to the limited spectral bandwidth in WSNs, existing multichannel MAC protocols designed for general wireless networks cannot be implemented in WSNs (Chang et al, 2017;Le and Rhee, 2010;Chang et al, 2009;García Algora et al, 2017;Khanian et al, 2016).…”

Efficient multichannel medium access control (MAC) protocols can significantly prolong the lifetime of sensor networks. In this paper, an energy-efficient prediction-based multichannel MAC protocol (PM-MAC) is proposed for large-scale wireless sensor networks (WSNs). PM-MAC minimises sensor node's idle listening time without introducing any multihop time synchronisation and channel assignment overhead by introducing a prediction mechanism of the target node's wakeup channel and wakeup time. PM-MAC introduces a dynamic channel allocation to achieve precise and quick resynchronisation when a prediction error occurs. In addition, in PM-MAC, the load can be well balanced on all channels. Finally, its prediction-based retransmission mechanism can achieve more energy efficiency in resolving severe wireless collisions caused by concurrent traffic in large-scale sensor network. The PM-MAC not only reduces multihop packet latency and energy consumption, but also increases network capacity and throughput. Experimental results confirm the outstanding performance of PM-MAC in all testbeds.
