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. 无线自组织网络 MAC协议 有限状态机 wireless self-organizing networks MAC protocol finite state machine 10.14188/j.1671-8836.2010.02.010 TN929.5 国防科技重点实验室预研基金资助项目（9140C1302010802） 2010-02-01 2021-04-01 2 56
