Multi-Channel Dynamic Scheduling has been centric stage of research in WSNs in recent years. In this paper, we propose a Distributed Multi-Channel Scheduling MAC communication protocol (DMS-MAC) to improve the network performance of WSNs, which selects the best channel for an individual wireless sensor node. DMS-MAC supports dynamic channel assignment mechanism where each sensor node is equipped with a directional antennas. The proposed protocol helps to decrease the probability of collision, interferences and improves the overall network performance of Wireless Sensor Networks (WSNs). The protocol is most suitable for short packet transmission under low traffic networks and has ability to utilize parallel transmission among neighboring nodes and achieves increased energy efficiency when multi-channels are available. Simulation result shows that the proposed protocol improves the performance of aggregate throughput, probability of successful transmission, packet delivery ratio, energy consumption and average end-to-end delay.
