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.
The finite state machine model is used to describe the implementation process of IEEE 802.11 MAC in wireless ad-hoc networks into different state transition processes, so as to establish a finite state machine model of MAC implementation in wireless ad-hoc networks. Under this model, How to successfully evade the detection and attack on the MAC protocol by attackers.NS-2.33 simulation results show that as the attackers attack the network nodes at different states, the routing cost increases and the average throughput of the network Showing a gradual downward trend.
