Estimating local coverage areas for location dependent queries
Jorge Bernad, Carlos Bobed, Eduardo Mena · 2018
Location-Based Services (LBS) are currently attracting many research efforts due to the pervasiveness of mobile devices in our daily life. Mechanisms to monitor distributedly the remote (and sometimes huge or dynamic) geographic areas referenced from location-based constraints are needed in order to retrieve the required data. In some cases (e.g., ad hoc networks), selecting the best places from which to scan a certain area is still an open problem; but moreover, it depends on another open problem: We should know the actual area that each object can scan (i.e., its communication coverage area) from its location in order to be sure that the whole interesting area is actually covered from a certain set of objects. Different disk-based coverage area models are usually adopted; however, knowing the real communication coverage area of an object is a very difficult task. Therefore, when accuracy is important, there is a need of a mechanism that estimates somehow the unknown real coverage area that a certain object is able to see, anytime and anywhere.
