In this paper, an exploratory study has been conducted to understand the various aspects of the network void problem. This paper provides insights into multiple research questions, which include how and why each void problem occurs. The authors have covered ten void problems (i.e., coverage voids or holes, routing voids or holes, jamming voids or holes, sink/black holes/worm holes, trap coverage, energy void or hole, joint coverage problem, sleep wake-up problem, barrier coverage problem and coverage restoration problem) and their definitions to understand how each problem affects the network performance, as well as the methods, approaches and algorithms used in preventing, defending and avoiding void problems.
