Nowadays, decentralized and dynamically changing wireless networks are mostly studied in works related to FANETs and VANETs, but such networks are not designed for controlling, monitoring or providing continuous end-to-end Internet access. We are studying network that has the same nature as FANETs and VANETs, i.e. consists of mobile nodes which can rapidly change their location, but in considered network each node is required to have reliable and high-bandwidth Internet access. The network in consideration is organized using IEEE 802.11p technology. Each node operates on area about 3 km in diameter and can either forward traffic or work as a traffic source. Unfortunately, during the experiment in real environment most nodes have not continuous Internet access, thus it is impossible to monitor link state of each node and identify the disconnect issue. In this paper a step-by-step analysis of node Internet access interrupt based on the node location and coverage zone estimation is presented. Equations for network topology generation for network emulation and modeling tools are presented as well. Also this paper contains network topological parameters discovered using experiments in real environment.
