摘要

目前,数字无线网络集中元同步随机多址的CSMA/CA类型引起了人们极大的兴趣,其有效性决定了通信会话的建立过程。同时,还没有对CSMA/CA型数字无线电通信网集中式元同步随机多址的有效性进行评估。此外,也没有评估攻击者的潜在破坏性行为对降低这种同步有效性的贡献。提出了随机多址访问CSMA/CA型介质的数字无线网络集中元同步分析模型。在该模型中,理论结果指标为同步包成功交付的概率,实验指标评价采用同步包成功交付的频率。该模型在已知概率指标的解析表达式中考虑了攻击者的潜在破坏性影响。提出了一种基于CSMA/CA的数字无线网络集中元同步随机多址的实验研究方法。最常见的网络数字无线电标准IEEE 802.11 (Wi-Fi)被认为是这样的网络。实验研究结果与理论研究结果略有差异,表明所建立的分析模型的充分性。首先,在数字无线电通信网络中,同步包的成功投递概率不依赖于用户终端的数量;其次,当用户终端传输数据包的平均持续时间小于0.85 ms时,建议采用非随机、预留的多址接入环境;第三,集中式同步具有抗破坏性影响的特点。该模型适用于CSMA/CA等随机多址数字无线网络的设计和网络运行优化。

Digital Radio Networks Centralized Elements Synchronization Model with Random Multiple Access to the CSMA/CA Type Medium
Currently, there is a great interest in digital radio network centralized elements synchronization with random multiple access to the CSMA/CA type , the effectiveness of which determines the process of establishing a communication session. At the same time, there was no assessment effectiveness digital radio communication network centralized elements synchronization with random multiple access to the CSMA/CA type. Also, there was no assessment made the contribution of potential destructive actions by the attacker to the reduction in the effectiveness of such synchronization. This paper presents digital radio networks centralized elements synchronization analytical model with random multiple access to the CSMA/CA type medium. In this model the theoretical resulting indicator is the probability of successful delivery of a synchronization package, and a package frequency of successful delivery is used in experimental indicator evaluation . The model takes into account the potential destructive effects of the attacker in analytical expressions for known probabilistic indicators. An digital radio network  centralized elements synchronization with random multiple access to a CSMA/CA type experimental study an environment is also presented. The most common network of digital radio standard IEEE 802.11 (Wi-Fi) is considered as such network. The experimental research results differ from the theoretical research results slightly, which indicates the adequacy of the developed analytical model. It was established, firstly, that the successful delivery probability of a synchronization packet does not depend on number of subscriber terminals in digital radio communication networks, secondly, with an average duration of a data packet transmission by such terminal less than 0.85 ms, it is advisable to use non-random, and the reserved multiple access to the environment, and, thirdly, centralized synchronization is resistant to destructive influences. The model is applicable in the design of digital radio networks with random multiple access to the medium such as CSMA/CA, as well as in optimizing the operation of such networks.
