Nowadays, industrial operations have become more complex, and managing resources and information flow is becoming increasingly important. One class of successful industrial applications is connected logistic processes that precisely organize flow of materials, related information, and activities between the points of origin and consumption to meet the requirements of customers or corporations. Communication technology plays an important role in this area and connects different sectors and levels of a smart process.

Assets and personnel management provides real-time visibility of fleet, processes, and value networks. This reduces labor, transportation, and installation costs while highly improving operation in remote sites. Currently, there are various services and techniques for asset management, personnel tracking, and identification of materials, inventory, and tools. GPS³ and public navigation services cannot meet the requirements applicable to most industrial applications and are not viable solutions for asset management in industrial applications. Some applications use wireless technologies such as Bluetooth, Wi-Fi, and ultra-wideband (UWB) for positioning and should be chosen according to the specific usage scenario [41, 42, 43]. In such techniques, precision, infrastructure demands, maintenance, and real-time requirements with respect to position update should be optimized. Since asset management is performed in smart environments where devices are often connected, four main features should be considered: ubiquitous connectivity, power efficiency, security, and reliability [44]. In this context, the usage of wireless communications is highly beneficial, especially in remote areas.
