A practical data driven approach for the deployment of WSNs on realistic terrains

Abstract: Existing works on relay nodes placement in two-tiered wireless sensor networks (WSNs) assume two-dimensional terrains and ignore completely the impact of the topography on the communication quality. In contrast, this paper addresses constrained versions of the relay nodes placement problem while adopting more realistic assumptions. To ensure the connectivity of a two-tiered WSN deployed on a three-dimensional terrain, the proposed approach determines the relay nodes positions by analyzing the data extracted fr… Show more

“…Table 1 summarizes the proposed approaches for RN-based clustering of WSNs, for which we mention again the following shortcomings. First, except for some works that consider 3D RoI 13 or very specific RoI, 15,16 most existing approaches are designed and evaluated under the assumption that the RoI is 2D. Consequently, these approaches are inapplicable for a realistic 3D RoI.…”

“…Nevertheless, its extension for 3D RoIs is really difficult because the identification of the RNs positions is based on the Jarvis March algorithm, 26 which is a geometric method that is only applicable for specific or purely 2D surfaces. Similarly, our previous work 13 is the only one that takes into account the topography impact, by representing the 3D RoI by a Triangulated Irregular Network (TIN) model and considering that two nodes can communicate only if they are intervisible. However, as mentioned in Table 1, this work ensures only simple connectivity and ignores completely the fault-tolerance problem.…”

“…In addition, these approaches suffer from a problem of practicalness, due to the omission of certain constraints having a quasi-permanent presence in real-life applications, or because of the adoption of unrealistic assumptions. For instance, excepting some works [3], [39], [30] that considered 3D or very specific RoI, all mentioned approaches are designed and/or evaluated under the assumption that the RoI is purely 2D, which makes them irrelevant for realistic 3D RoI, and limits their usage to very limited cases.…”
