“…9 Collection tree routing is widely used in WSNs, especially in data collecting applications of WSNs. 10 A lot of research works have been done on optimizing the collection tree for maximizing network lifetime. The literature [11][12][13] studied the lifetime maximization of WSNs with data aggregation at relay nodes.…”

Routing optimization in wireless sensor networks facilitates to reduce the overhead of the maintaining of wireless sensor networks and extend the lifetime of wireless sensor networks. Collection tree-based routing protocol, which does not require route discovery, has been widely used for low overheads of calculation and storage. However, with collection tree-based routing protocol, some nodes easily become the bottleneck points and quickly run out of the energy. To deal with this drawback, this article proposes a collection tree-oriented mesh routing strategy with cooperatively consuming the residual energy among the neighboring sensor nodes. The collection tree-oriented mesh routing is formulated into a linear programming problem with the purpose to maximize the network lifetime. By solving the optimization problem, the optimal mesh routing and data forwarding scheme is derived. Experimental simulations show that the proposed collection tree-oriented mesh routing optimization strategy can extend the network lifetime by more than 20%.

“…The present work has analyzed temperature values recorded by a monitoring system based on IoT, previously developed by our team [ 48 ], to have a fully functional demonstrator to test these techniques and to also address the problems identified by other authors in similar situations [ 40 , 49 , 50 , 51 ]. With this monitoring experiment, comprised of 26 wireless sensor nodes, we intended to demonstrate the usefulness of this technology by collecting the temperatures at different points and heights of the church.…”

Adequate thermic conditions are required for the preventive conservation of artworks, but such optimum conditions cannot always be achieved in historical buildings such as ancient churches. In those cases, it is of interest to assess the potential risk of punctual changes in indoor environments that can be harmful to artworks. These conditions can be assessed by means of a microclimate monitoring system comprised of a set of energy-efficient wireless sensors connected to the cloud using IoT techniques. This approach was followed at the baroque church of Saint Thomas and Saint Philip Neri in Valencia (Spain). A set of 26 wireless nodes was installed, which recorded values of temperature and relative humidity every hour for a period of 7 months. Small differences of temperature were obtained among sensors, so that an efficient methodology based on principal component analysis (PCA) was applied for the characterization of similarities and dissimilarities between sensors. Daily ranges of temperatures were studied as well as mean trajectories, differences between days of the week, and changes in the correlation structure of daily median values over time. Results provide a framework for an efficient characterization of temperatures in heritage buildings based on a network of wireless sensors. Such a framework is useful to assess the potential risk of temperature fluctuations on the preventive conservation of historical buildings and artworks.

“…Contrasted against the available commercial devices, research work in recent years has explored taking an IoT approach in developing lightweight wireless sensor networks (Agbota et al, 2014;Aparicio et al, 2016;Peralta et al, 2013) capable of collecting environmental data within cultural heritage organizations and spaces, which may be remote, lack network or power access or otherwise be difficult to monitor. Prior work has deployed novel systems to collect environmental data in museums (Bacci et al, 2008;Londero et al, 2016;de Brito et al, 2008;Leccese et al, 2014), including the light levels near artworks (Zhang and Ye, 2011), the conditions of the buildings themselves (D'Amato et al, 2012;Mecocci and Abrardo, 2014;Mesas-Carrascosa et al, 2016) and for surveillance purposes (Viani et al, 2012).…”

Purpose Cultural heritage archives rely on environmental monitoring devices, such as dataloggers or more complex networked systems, to ensure collection preservation through collecting temperature, humidity, light and/or air quality measures. Existing systems are often costly, inflexible and do not use a modern, internet of things (IoT) approach. This paper aims to determine the suitability of currently popular general-purpose IoT devices, standards and technologies to the environmental monitoring needs of archivists, as well as identify any challenges. Design/methodology/approach This paper describes an exploratory study detailing the design, construction and usability testing of a do-it-yourself datalogger and data dashboard system, which seeks to manage previously identified trade-offs in cost, required technical skill and maintainability. Findings The environmental monitoring system presented met archivists’ needs well and was generally noted to be easy-to-use, efficient and an improvement on existing systems. This suggests that an IoT approach can support archivists’ needs in this area. Research limitations/implications Potential limitations of this study include lack of archival staff with sufficient technical training to maintain such a system and the rapid pace of IoT evolution yielding unstable and constantly changing technologies. Practical implications The system design presented in this work provides a blueprint for cultural heritage organizations desiring a fuller-featured, lower cost environmental monitoring system for archival collections. Originality/value This research takes a novel user-centered, open-source, IoT approach to construct an environmental monitoring system that is designed directly from archivists’ requirements and is extensible for future needs.
