A Greener MAC Layer Protocol for Smart Home Wireless Sensor Networks

The wireless sensor network (WSN) is an important element on many advanced, energy efficient data acquisition (DAQ), and control systems. Sleep/wake-up scheduling and network overhead are some of the major burdens to achieve energy efficient WSNs. In this paper, an energy efficient communication algorithm is proposed for smart home sensor networks. The proposed approach targets the wasted energy during the idle listening, collision, and overhearing processes. A three-tier Medium Access Control (MAC) protocol has been developed to minimize the total energy consumption of the network. The new protocol reduces the total energy requirement by each node, facilitates confirmed communication for steady traffic, and gives adaptive control during varying traffic load. Overall, the proposed MAC protocol shows better performance than conventional WSN protocols.

无线传感器网络（WSN）是许多先进的、节能的数据采集（DAQ）和控制系统的重要组成部分。睡眠/唤醒调度和网络开销是实现节能无线传感器网络的一些主要负担。在本文中，针对智能家居传感器网络提出了一种节能通信算法。该方法针对空闲监听、冲突和串音过程中浪费的能量。开发了一种三层介质访问控制（MAC）协议，以最小化网络的总能耗。新协议降低了每个节点的总能量需求，促进了稳定流量的可靠通信，并在不同流量负载期间提供自适应控制。总体而言，所提出的MAC协议比传统的无线传感器网络协议表现出更好的性能。
