在网络QoS研究领域,大量的研究工作都集中于传统的QoS需求所定义的度量,如时延、带宽和丢失率等;另一方面,由于无线信道和节点移动等原因,移动无线网络的安全问题更加突出。 In the field of network QoS research, a great deal of research work focuses on the metrics defined by traditional QoS requirements such as delay, bandwidth and loss rate. On the other hand, due to the reasons such as the movement of wireless channels and nodes, the security of mobile wireless networks The problem is more prominent.
