摘　　要：针对无线传感器网络中恶意节点产生的选择性转发攻击行为,该文提出一种有效的攻击检测方法。该方法将简化云模型引入信任评估中,结合改进的K/N投票算法确定目标节点的信任值,将目标节点信任值与信任阈值比较,进行选择性转发攻击节点的判定。仿真结果表明,当信任阈值为0.8时,经过5个时间段后,该方法能够有效地检测出网络中的选择性转发攻击节点,具有较高的检测率和较低的误检率。For the selective forwarding attack behavior generated by malicious nodes in wireless sensor networks,an efficient detection method is proposed.The simplified cloud model is introduced into the trust evaluation model,and the improved K/N voting algorithm is used to obtain the trust value of the target node.Then,the trust value of the target node is compared with the trust threshold to identify the attack node.The simulation results show that when the trust threshold is 0.8 and after 5 time periods,the proposed method can effectively detect the selective forwarding attack nodes,and it has high detection rate and low fault rate.
