Abstract:
The authors overview mobility models which are applicable for simulation of movement of users' devices in a fifth generation (5G) wireless network. Mobility patterns that are typical for simulating the behavior of users of a wireless ad hoc network are considered. The features of the models are discussed, both for individual motion of objects and for motion of groups of objects, from the point of view of appliance to the analysis of interference in wireless networks. The purpose of the paper is to propose a number of mobility models for making an informed decision when choosing a model for evaluating the quality of service in 5G wireless networks. The authors present simulation results that illustrate the method of estimation of the key performance quality parameter, i. e., signal to interference ratio. For illustration, the developed complex of analytical and simulation models is used for simulation of movement of shopping moll customers with the help of the grid random walk mobility model.
Keywords:
entity mobility model, group mobility model, ad hoc network simulation, signal to interference and noise ratio, SINR.
