Analytical-Statistical Model of Mesh Network Survivability Evaluation
Introduction: Modeling wireless telecommunication networks with mesh topology in order to assess the quality of their operation is an important problem. Self-organizing architecture provides the survivability of a mesh network, making sure that the basic functions of data delivery are still supported even when individual network elements are lost. Purpose: The goal is to develop an analytical-statistical model to assess the survivability of telecommunication networks with mesh topology. Results: A simulation model is proposed which implements an analytical-statistical approach to the assessment of survivability of a telecommunications network with mesh topology. The quantitative criterion is the connection establishment probability, and the qualitative criterion is providing the network to the subscribers within a given time interval starting from the moment the call was received. Taking into account the real conditions in a mesh network (dynamic routing, abrupt changes in the network load, loss of individual network elements), the proposed model allows you to estimate the time of connection establishment and, depending on the result, to choose technical parameters in order to provide an acceptable connection establishment time and a certain probability of guaranteed call delivery. Practical relevance: The model can be used to build mesh networks with specified characteristics of their functioning quality.
