【摘要】：在无线传感器网络(Wireless Sensor Networks,WSNs)中引入移动节点可以极大地提升网络性能。然而,移动节点一旦被蠕虫感染则会大大加快蠕虫在WSNs中的传播。针对这一新的研究问题,该文分2步来抑制和清理移动蠕虫传播源。首先建立了移动蠕虫感染模型,设计启发式算法以确定移动感染区域的边界,通过挂起感染边界附近的高风险节点来阻断蠕虫的进一步传播。第2步设计定向扩散的良性蠕虫对网络中被感染的节点进行修复,以彻底清除蠕虫病毒。理论分析和仿真实验结果均表明,该文所提方法能够在付出较小的代价下达到较好的移动蠕虫清理效果,适合能量受限的无线传感器网络。
[Abstract]:The introduction of mobile nodes in Wireless Sensor Networks (WSNs) can greatly improve network performance. However, once the mobile node is infected by the worm, it will greatly accelerate the spread of the worm in WSNs. To solve this new problem, this paper consists of two steps to suppress and clean up the source of mobile worm propagation. First, a mobile worm infection model is established, and a heuristic algorithm is designed to determine the boundary of the mobile infection area, and to block the further spread of the worm by suspending the high-risk nodes near the infection boundary. The second step is to design a directional spread benign worm to repair the infected nodes in the network to eliminate the worm virus completely. Theoretical analysis and simulation results show that the proposed method can achieve a better mobile worm cleaning effect at a lower cost and is suitable for energy-constrained wireless sensor networks.
