摘要: 针对无线传感器网络的选择性转发攻击,以提高恶意节点检测率和系统防御性为目标,提出了一种基于最优转发策略的随机路由算法和可信邻居节点监听的检测和防御方法。该方法通过引入距离、信任度等参数构建转发路径,同时,在路由发现和选择过程中,采用节点监听机制对恶意节点进行检测和防御处理。在Matlab环境下对该机制进行了仿真实验,并与其他方法进行了性能对比分析。实验结果表明:该方法能够在消耗相对较少能量情形下有效检测出选择性传递攻击,保持较高事件报文成功率,并且对恶意节点能做到有效的防御和处理。

Abstract: To improve the detection rate for malicious node and the defensive ability of system,a detection method based on optimal random routing algorithm and neighbor node monitoring was proposed, which was against the selective forwarding attack about Wireless Sensor Network (WSN). This method created the forward path by introducing some parameters such as distance, trust degree, etc. At the same time, it also used the node monitor scheme to detect and defend malicious node during the routing discovery and selection process. Simulation was completed at Matlab environment and performance comparison was done with other methods. Analysis and simulation results show that this method is effective for detecting selective forwarding attack and can ensure reliable packets delivery to destination using relatively less energy.
