Review of Mobile Connectivity Persistence Technologies for Dynamically Changing Networks' Availability Scenarios

Given the variety of network connectivity options for mobile devices, dynamically choosing the most optimal connection between multiple alternatives is not a simple process. In heterogeneous networks with changing availability the decision process plays a significant role in ensuring a persistent and seamless connection. This study analyses existing technologies and methods for evaluating the quality of computer network connections aimed at finding the best time to change networks and selecting the best connection available at a given time. A study of theoretical literature is carried out, examining the selection method processes and their importance in ensuring mobility. The most universal in the context of this study is found to be the SAW method.
