In the last decade, we have seen the uptake of connected solutions to support and improve manufacturing, warehousing and distribution operations in industry. However, deterministic and reliable wireless communication in large-scale, dynamic and mobile applications still remains one of the greatest challenges for the realization of the Digital Factory of the Future. In this paper, we investigate more...
Wireless network deployments in industry often grow organically with new technologies added over time, among which many use the non-licensed spectrum to avoid licensing costs. As a result, technologies competing for the same spectrum end up deployed in the same area, causing coexistence problems to manifest themselves at a later stage. To avoid unexpected performance degradation, there is a need to...
Because of the recent advances in wireless technologies and, consequently the fast growing number of wireless devices that are being deployed in consumer houses, there is a growing demand from manufacturers to develop and deploy tools able to diagnose problems and evaluate the performance of their products prior to releasing them to the market. Such testing tools are required to be quickly deployable...
The Constrained Application Protocol (CoAP) is a new Internet protocol that is currently being standardized. CoAP allows access to the drastically increasing number of smart objects and their sensing resources from virtually anywhere. It is a light-weight protocol designed to cope with the restrictions imposed by the limited resources (CPU, memory, power) of many smart objects. Depending on the application,...
Next-generation wireless sensor networks will be used for many diverse applications in time-varying network/environment conditions and on heterogeneous sensor nodes. Although Quality of Service (QoS) has been ignored for a long time in the research on wireless sensor networks, it becomes inevitably important when we want to deliver an adequate service with minimal efforts under challenging network...
Wireless sensor networks today are used for many and diverse applications like nature monitoring, or process and wireless building automation. However, due to the limited access to large testbeds and the lack of benchmarking standards, the real-life evaluation of network protocols and their combinations remains mostly unaddressed in current literature. To shed further light upon this matter, this...
