IEEE802.11无线局域网业务量特性分析及其自相似性研究

Analysis of Traffic Characteristic of IEEE802.11WLAN and Study of its Self-similarity

本文通过对IEEE无线局域网业务量的一系列实际测试,对IEEE802.11的业务量的特性进行了分析,对试验结果做出了解释,更重要的是,通过对试验结果的进一步分析,本文发现两个802.11设备间的业务量特性呈现出显著的自相似性。最后,作为建立基于自相似理论的802.11业务量数学模型的初步尝试,给出并验证了丢包率PLR与分配给该无线链路的带宽之间具体的函数关系。

Through a series of real tests,this paper analyses the characteristic of IEEE 802.11 traffic,explains the results of the tests. More importantly,the results indicate that the characteristic of IEEE 802.11 traffic exhibits obviously self;similarity. As the first step to set up a 802.11 traffic math;model based on self;similarity theory,this paper establishes and verifies a function relation between PLR(Packet Loss Rate) and assigned bandwidth to that wireless link.
