摘要

本文提出的 LTH-MAC(低流量感知混合 MAC)是一种新型 MAC 协议,旨在提高无线传感器网络(WSN)的能效和信息传输可靠性。LTH-MAC 通过灵活时隙、信道选择、避免碰撞、并行传输和高效回退方案等创新技术实现了这一目标。这些优化措施减少了空闲监听、减少了碰撞并简化了同步。使用 OPNET 环境进行的仿真表明,LTH-MAC 能显著降低能耗,尤其是在轻流量负载下。此外,与 ECoMAC 相比,LTH-MAC 可提供更低的端到端延迟和更高的信息传递可靠性。这些进步使 LTH-MAC 成为要求高效可靠通信的 WSN 应用的理想解决方案。

Low-Traffic Aware Hybrid MAC (LTH-MAC) Protocol for Wireless Sensor Networks
This paper proposes LTH-MAC (Low-Traffic Aware Hybrid MAC), a novel MAC protocol designed to improve energy efficiency and message delivery reliability in Wireless Sensor Networks (WSNs). LTH-MAC achieves this through innovative techniques like flexible timeslots, channel selection, collision-avoiding, parallel transmissions, and efficient backoff schemes. These optimizations lead to reduced idle listening, minimized collisions, and simplified synchronization. Simulations using OPNET environment demonstrate that LTH-MAC significantly reduces energy consumption, especially under light traffic loads. Additionally, LTH-MAC provides lower end-to-end latency and higher message delivery reliability compared to ECoMAC. These advancements position LTH-MAC as a compelling solution for WSN applications demanding efficient and reliable communication.
