| Popis: | The model of resource allocation and sharing for conjoint servicing of real time and batched NB IoT trafic streams over LTE cell facilities is constructed. In the model three types of trafic flows are considered. The irst two represent the flows of sessions coming from wireless video surveillance cameras. Depending on the number of trafic sources the flows are described by Poisson or Engset models. The resource of the cell is also used by flow of sessions coming from NB-IoT sensors. This flow follows Poisson model with batch arrivals and possibility of waiting if available radio resource is occupied. The number of waiting places and maximum allowed time of waiting are restricted. All random variables used in the model have exponential distribution with corresponding mean values. Using the model the main performance measures of interest are given with help of values of probabilities of model's stationary states. The model and derived algorithms of characteristics estimation can be used for study the scenarios of resource sharing between LTE and NB-IoT trafic flows. |
