Recently, technology has become more attractive for industry by paving the way to new applications, which go well beyond traditional sensor applications. These applications can be classified in different categories: monitoring, alerting, healthcare assistance, and actuating, among others. A Wireless Sensor Network (WSN) is feasible for the heritage scenarios protection and for monitoring because its specificity, autonomy, self-configurability, lasting lifetime, and mobility. However, their services, protocols, and architectures have constraints to support new issues for monitoring cultural assets: geographical dispersion, insufficient resources, and not enough staff to protect all the monuments and to provide tourist information broadcasting. We propose a modular system. It consists of three elements: a WSN, a “Central System,” and a novel platform named “Local Node Gateway.” It allows the coexistence of different wireless technologies in order to provide actuation, processing and communication functionalities. This proposal takes a new approach to solve these heritage-monitoring problems.
