Wireless sensor networks are appealing to researchers due to their wide range of application. This paper proposes Variable Grid-quorum Pattern MAC protocol (VGP-MAC), an adaptive, asynchronous and low-latency MAC protocol designed for wireless sensor networks. VGP-MAC improves the pattern and timeslot schedule, which make nodes save energy by the proper sleep mechanism according to the nodes' own traffic. And the grid quorum-based mechanism solves the asynchrony in the multi-hop wireless sensor network. This paper develops a better pattern and schedule generation schemes with less state transformation frequency. The analytical and experimental results show that VGP-MAC obtains more energy savings and reduces the latency.
