摘　　要：研究基于IEEE 802.15.4协议的无线传感器网络蠕虫传播方法,并根据IEEE802.15.4的固有特性,提出了网络环境自适应的节点免疫算法,算法通过本地及邻居信息选择免疫节点控制蠕虫的传播.针对提出的算法存在免疫过程容易陷入局部度风险最大点的问题,借鉴模拟退火算法的基本原理,提出了改进的自适应免疫算法.仿真实验表明,本文提出的算法可以通过免疫少量的节点有效的抑制蠕虫的扩散,提高了无线传感器网络抵抗蠕虫攻击的能力.The worm propagation method for wireless sensor networks based on IEEE 802.15.4 protocol was presented.Accordingly,an environment adaptive immunization algorithm was proposed by taking advantage of inherent characteristics of IEEE 802.15.4.The proposed algorithm choosed immune nodes according to local and neighbor information to control the propagation process.In order to solve the problem that iterative process was easy to fall into local node with maximum risk value,an improved adaptive algorithm was proposed by learning from the basic principle of the simulated annealing algorithm.The experimental results show that the proposed algorithms can efficiently stop the epidemic of worm with a minimal number of immunizations which enhance the wireless sensor networks＇ ability to resist worm attack.
