A4WSN: an architecture-driven modelling platform for analysing and developing WSNs

Abstract

This paper proposes A4WSN, an architecture-driven modelling platform for the development and the analysis of Wireless Sensor Networks (WSNs). A WSN consists of spatially distributed sensor nodes that cooperate in order to accomplish a specific task. Sensor nodes are cheap, small, and battery-powered devices with limited processing capabilities and memory. WSNs are mostly developed directly on the top of the operating system. They are tied to the hardware configuration of the sensor nodes and their design and implementation can require cooperation with a myriad of system stakeholders with different backgrounds. WSNs peculiarities and current development practices bring a number of challenges, ranging from hardware-software coupling, limited reuse, late WSNs quality property assessment. As a way to overcome a number of existing limitations, this study presents a multi-view modelling approach that supports the development and analysis of WSNs. The framework uses different models to describe the software architecture, hardware configuration, and physical deployment of a WSN. A4WSN

A Model-Driven Methodology to Accelerate Software Engineering in the Internet of Things

“…Hence, higher abstractions are needed, free from the technical considerations to enable seamless wiring. The existing approaches for network modeling are disparate; some approaches target Wireless Sensor Networks (WSN) [37], [38] (a network of many tiny sensors dedicated 1 https://github.com/TelluIoT/ThingML to collect data) [39], others target the web of things [40] (i.e., the IoT using existing web technologies), and others target a specific category of IoT applications such as Smarthomes or TinyOS-based things [41], [31], [30], [32]. According to our literature review, we noticed a lack of a full-scale, documented, and open-source approach for modeling a network of things generically.…”

WSN Simulators Evaluation: an Approach Focusing on Energy Awareness

“…NS2 is the simulator used in [39] to analyse S-MAC and leach in WSNs. An architecture-driven modelling platform, called A4WSN, for analysing and developing WSNs is presented in [40]. In [41], the support for heterogeneous networks in IDEA1, is presented.…”
