Real-Time Prototyping of Matlab-Java Code Integration for Water Sensor Networks Applications

Abstract

Industrial applications typically necessitate the interaction of heterogeneous software components, which makes the design of an integrated system a demanding task. Specifically, although Matlab ® and Java are among the most commonly used programming languages in industrial practice, with each one offering its own advantages, however, their integration for realtime code prototyping is not straightforward. Motivated by this problem, this work proposes an efficient method based on the use of sockets to integrate Matlab and Java code for designing a data processing platform tailored to smart water sensor networks scenarios. The performance of the proposed approach is evaluated on two distinct tasks, namely, the recovery of missing values and the temporal super-resolution from streaming data. Experimental evaluation with real pressure data reveals the superiority of our methodology, in terms of reduced execution times, when compared against two well-established alternatives, namely, the use of standalone applications using input-output files for executing Matlab code in Java-based environments and socket-based solutions implemented directly in a Matlab environment.Index Terms-Matlab-Java code integration, client-server model, real-time prototyping, water sensor networks

Quantifying the Computational Efficiency of Compressive Sensing in Smart Water Network Infrastructures

“…The smaller is the µ, the more incoherent are the two matrices. We emphasize that the data compression, which is performed onboard the sensors, consists only of a simple matrix-vector multiplication as expressed by Equation (4). The utilization of the sparsifying basis Ψ is required only during the decompression phase (see the next section), which is carried out at the control center.…”
