A Reconfiguration Approach Using Ontologies to Save Energy on WSNs

摘要

Wireless Sensor Networks (WSNs) have a very large growth in research in recent years. They are essentially ad-hoc networks, capable of processing, sensing and transmitting wireless information. These are networks where the specificity of applications becomes something common, due to various types of restrictions (e.g., processing, bandwidth, etc), and energy consumption is the most important restriction. Trying to solve this problem, we present a new approach to saving energy in WSN, based on automatic sensors reconfiguration. Our approach consists of three components: a middleware to handle the heterogeneity of data and applications, an ontology to give a formal semantics to data and a reconfiguration module to communicate with ontology and middleware, and process queries. Some assessments were made in order to show its feasibility, using a case study based on energy consumption. Finally, we argue that its use is feasible and attractive.
