Wireless sensor networks (WSNs) are widely used in various fields, and the reliability and performance of WSNs are critical for their applications. However, WSNs are vulnerable to jamming attacks, and the impact of movable jammers on WSNs' reliability and performance remains largely unexplored. This study aims to investigate the impact of movable jammers on WSNs and propose a comprehensive approach for modeling jammer-affected WSNs, comprising four parts. Firstly, agent-based modeling of sensor nodes, base stations, and jammers has been proposed. Secondly, a jamming-aware routing protocol (JRP) has been proposed to enable sensor nodes to weigh depth and jamming values when selecting relay nodes, thereby bypassing areas affected by jamming. The third and fourth parts involve simulation processes and parameter design for simulations. The simulation results show that the mobility of the jammer significantly affects WSNs' reliability and performance, and JRP effectively bypasses jammed areas and maintains network connectivity. Furthermore, the number and deployment location of jammers has a significant impact on WSNs' reliability and performance. These findings provide insights into the design of reliable and efficient WSNs under jamming attacks.
无线传感器网络(WSNs)被广泛应用于各个领域,其可靠性和性能对于其应用至关重要。然而,WSNs 容易受到干扰攻击,可移动干扰器对 WSNs 的可靠性和性能的影响在很大程度上尚未得到探索。本研究旨在调查可移动干扰器对 WSNs 的影响,并提出一种全面的方法来对受干扰影响的 WSNs 进行建模,包括四个部分。首先,提出了基于代理的传感器节点、基站和干扰器的建模。其次,提出了一种感知干扰的路由协议(JRP),使传感器节点在选择中继节点时能够权衡深度和干扰值,从而绕过受干扰的区域。第三和第四部分涉及模拟过程和参数设计。仿真结果表明,干扰器的移动性对 WSNs 的可靠性和性能有显著影响,JRP 有效地绕过了干扰区域并保持了网络连接。此外,干扰器的数量和部署位置对 WSNs 的可靠性和性能有重大影响。这些发现为设计在干扰攻击下可靠高效的 WSNs 提供了思路。
