无线传感器网络拥塞区域快速节能映射技术

Fast and energy-efficient technique for jammed region mapping in wireless sensor networks

Nabila Rahman, Matthew Wright, Donggang Liu

摘要:

无线传感器网络(WSNs)对于监控系统通过获取和发送关于安全区域中的任何入侵的信息来执行监控具有重要的实际意义。很少需要人为干预是无线传感器网络最理想的功能之一,因此使其成为保护国际边界等大片区域的更便宜,更安全的替代方案。无线传感器网络中的干扰攻击可以用来破坏网络中传感器节点之间的通信。由于难以防止干扰攻击,检测和绘制出的干扰区域是克服这个问题的关键。在安全监控场景中,一旦网络运营商知道网络中的拥塞区域,他们将能够采取适当的措施来对抗拥塞。还期望保持网络中的传感器节点的交互最小化,因为它们是低功率设备并且需要保存它们的资源。在本文中,我们提出了一个轻量级的技术,更快地映射的堵塞区域。我们通过消除从网络到中央基站(BS)的映射的实际责任来最大限度地减少传感器上的负载。在少数节点向BS报告后,BS执行网络中拥塞区域的映射任务。我们使用我们的仿真结果来比较我们提出的系统与现有的技术,也来衡量我们的系统的性能。我们的研究结果表明,在网络中的拥塞区域可以映射从较少的节点报告给基站。

英文摘要:

Wireless sensor networks (WSNs) have great practical importance for surveillance systems to perform monitoring by acquiring and sending information on any intrusion in a secured area. Requirement of very little human intervention is one of the most desirable features of WSNs, thus making it a cheaper and safer alternative for securing large areas such as international borders. Jamming attacks in WSNs can be applied to disrupt communications among the sensor nodes in the network. Since it is difficult to prevent jamming attacks, detection and mapping out the jammed regions is critical to overcome this problem. In a security monitoring scenario, the network operators will be able to take proper measures against jamming once the jammed regions in the network are known to them. It is also desirable to keep the interactions of the sensor nodes in the network minimal, as they are low powered devices and need to conserve their resources. In this paper we propose a light-weight technique for faster mapping of the jammed regions. We minimize the load on the sensors by removing the actual responsibility of mapping from the network to the central base station (BS). After a few nodes report to the BS, it carries out the task of mapping of the jammed regions in the network. We use our simulation results to compare our proposed system with the existing techniques and also to measure the performance of our system. Our results show that the jammed regions in a network can be mapped from fewer nodes reporting to the base station.
