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.
