摘要
利用有限状态机模型,将无线自组织网络IEEE 802.11 MAC协议的实现过程描述成不同的状态转移过程,从而建立了无线自组织网络MAC协议执行过程的有限状态机模型.在此模型下,研究了攻击者如何成功地逃避检测及对MAC协议的攻击行为.NS-2.33仿真实验表明,随着攻击者在不同状态下对网络节点的攻击程度的加强,路由消耗逐渐增大,网络的平均吞吐量呈逐渐下降趋势.
By using the model of Finite State Machine,operation processes of the IEEE 802.11 MAC protocol in wireless self-organizing networks are described as different state transitions.Based on this description,a Finite State Machine model of MAC protocol in wireless self-organizing networks is established.Under this model,how attackers successfully avoid being detected and make efficient attacks to a MAC protocol is studied.A simulation with NS-2.33 shows that the average throughput of the network decreases while the consumption of the route increases gradually as attacks are strengthened.
