Abstract

The Internet of Underwater Things (IoUT) is transforming underwater communication by enabling essential mission-critical applications such as precise navigation, emergency response coordination, diver safety, robust security and surveillance systems, and real-time environmental monitoring. However, Underwater Acoustic Communication (UAC), which serves as the primary communication medium for IoUT, experiences substantial challenges, including limited bandwidth availability, severe signal attenuation and Doppler-induced frequency shifts, especially pronounced in mobile underwater environments. These challenges degrade throughput and increase latency, making it difficult to meet the strict delay and reliability demands of mission-critical IoUT applications. Without adaptive solutions, real-time underwater communication remains unreliable and inefficient. This paper introduces an Adaptive Guard band and Power control resource allocation scheme for mission critical applications (AGP-MCA), specifically designed to improve underwater communication. The AGP-MCA framework optimizes the acoustic spectrum based on the criticality of IoUT applications. AGP-MCA dynamically adjusts guard bands to effectively mitigate Doppler caused by mobile nodes and strategically manages transmission power to reduce power consumption significantly, and handles non-critical data through buffering. We formulate a comprehensive mathematical optimization model and employ a Whale Optimization Algorithm (WOA)-based meta heuristic approach to achieve near-optimal solutions while ensuring minimal computational complexity. Extensive simulations demonstrate that AGP-MCA enhances throughput, reduces both end-to-end delay and power consumption, and consistently outperforms existing protocols and configurations without adaptive guard bands. Further, it offers a robust and power-efficient solution for real-time mission-critical IoUT applications.

移动和固定关键任务IoUT网络中资源分配的自适应保护带和功率控制

水下物联网（IoUT）通过实现精确导航、应急响应协调、潜水员安全、强大的安保和监控系统以及实时环境监测等关键任务应用，正在改变水下通信。然而，作为IoUT主要通信媒介的水声通信（UAC）面临着巨大的挑战，包括有限的带宽可用性、严重的信号衰减和多普勒诱发的频移，尤其是在移动水下环境中。这些挑战降低了吞吐量并增加了延迟，使其难以满足关键任务IoUT应用程序的严格延迟和可靠性要求。如果没有自适应解决方案，实时水下通信仍然是不可靠和低效的。本文介绍了一种用于关键任务应用的自适应保护带和功率控制资源分配方案（AGP-MCA），专门用于改善水下通信。AGP-MCA框架基于IoUT应用的临界性优化了声学频谱。AGP-MCA动态调整保护带，有效缓解移动节点引起的多普勒效应，战略性管理传输功率，显著降低功耗，并通过缓冲处理非关键数据。我们制定了一个全面的数学优化模型，并采用基于鲸鱼优化算法（WOA）的元启发式方法来获得接近最优的解决方案，同时确保最小的计算复杂度。大量的仿真表明，AGP-MCA提高了吞吐量，降低了端到端延迟和功耗，并且在没有自适应保护带的情况下始终优于现有协议和配置。此外，它还为实时任务关键型IoUT应用提供了强大且节能的解决方案。
