Plataforma de evaluación de mecanismos de localización de nodos, en redes de sensores inalámbricos bajo el agua (UWSN).

Abstract

In the present investigation, the evaluation of the mechanisms of localization of nodes in Networks of Wireless Sensors Under Water (UWSN) was carried out using an experimental methodology based on the measurement of specific variables such as: delay, energy consumption and throughput, that determine the performance of the network with each of the routing methods analyzed: Vector-Based Forwarding (VBF), Jump to Hop Vector-Based Forwarding (HH-VBF), Focused Beam Routing Protocol (FBR) and Sectoral Routing with Destination Location Prediction (SBR-DLP). For the execution of the performance tests, a simulation environment with characteristics of a real environment was established and in order to contribute to the preservation of the flora, fauna and its fragile ecosystem, the Galapagos Islands have been selected as a possible scenario for application that proposes a network scheme composed of 99 sensor nodes and a sink node fluctuating at different depths and speeds, covering an extensive area of 1000m x 1000m x 500m (length, width, depth). Using the Aqua Sim simulator, the one-way ANOVA variance method and the Post hoc HSD Tukey test results in the fact that for a Mobile Dense Network with marine currents of speed (0.1 and 1.2) m/s, the protocol that highlights its performance and energy savings compared to the others evaluated is VBF obtaining a delay of 154.48ms, throughput of 38.02 bps and energy consumption of l, 154W / s. Based on the present study, entities such as the INOCAR (Navy Oceanographic Institute) could implement a technological platform with reduced energy consumption, adequate transmission speed and minimum delay that through the remote control of underwater parameters allows the preservation of the Marine Environment.
