A Delay-Tolerant Framework for Integrated RSNs in IoT
Published in Fadi Al-Turjman, Multimedia-enabled Sensors in IoT, 2018
The second architecture (RS) integrates RFID readers with sensor nodes. Here, the existence of three types of devices is assumed: the integrated RFID RS nodes, simple RFID tags, and the sink or base-station (Figure 5.2). Mason et al. [18] introduced a prototype system for asset tracking with RFID and sensor networks. From a DTN perspective, providing integrated entities with extra buffering capacities may not present a design challenge since readers are already complex. However, depending on integrated RFID readers and sensors to provide connectivity over the disrupted topology is not a cost-effective approach, especially when considering the limited sensing range and power consumption of sensors. As mentioned earlier, RFID readers are the most complex and costly component of an integrated system. Considering an IoT layout in which sensors are usually abundantly deployed, integrating readers with sensors will lead either to inflating the deployment costs due to the sensors’ wide distribution or to depriving wide sections of the topology from the sensors’ coverage for the sake of reducing the subsequent cost of integrated readers. Each of these alternatives has its toll on the system's overall performance and efficiency. Again, the cost of this architecture will be dominated by the total of CRead + CXS.

CIIs can be exploited in the area of logistics, tracking, and fleet management in various and diverse ways [6–10]. Asset tracking is an already widely adopted application domain: location transmitters are installed on pallets, parcels, fleet, returnable containers, trolleys, etc., allowing for real-time knowledge of asset location. Besides location, sensors can report data such as temperature, humidity, tilt, providing full information on the transport conditions and improving safety of goods (extensively used in food transport). IoT can also enhance the security in the logistics domain, by providing the means for monitoring of intrusion or theft indications and reliably transmitting these signals to appropriate control centers. Moreover, the status and load of warehouses can be effectively monitored resulting to their usage being optimized. Similarly, the status of traffic, information for possible congestions, and parking space availability can be used to optimize vehicle movement and transports. With respect to fleet management, (i) fleet operations can be optimized by streamlining logistics using real-time data and alerts to optimize delivery routes, monitor performance, and quickly respond to delays or issues as they happen, (ii) vehicle performance can be maintained through predicting and monitoring maintenance needs, driver status and behavior, fixing of potential issues, etc. Overall, clear visibility of all assets and the movement and status of goods at all stages of the logistics journey can be gained. In all cases, sensors are deployed on assets or information collection points, and data are collected from them and subsequently processed. Actuators may also be present and driven accordingly, to perform physical actions that affect the environment.
Substation Asset Management

For almost all power equipment, expected lifetimes are decades long. Deterioration rates are quite slow, and often their effects subtle and hard to measure. For this reason, a lot of historical data are typically required to built a base from which analysis can determine trends and sustainable points. An asset tracking database is useful for monitoring condition and triggering proactive service and usually more than pays for itself in reduced costs.
Handheld Technology Selection, Evaluation, and Risk Mitigation Using Stochastic Analytical Hierarchical Process: A Standardization of the Request for Proposal Process

Ruggedized handheld devices are used in numerous manufacturing, material handling, retail, and service-based organizations to perform tasks such as asset tracking, inventory management, communication, and remote and training assistance (Burch et al., 2019). Given their ability to work in harsh environments, these ruggedized handheld devices add enhanced competitiveness to industrial organizations while offering the real-time process enhancements of continued connectivity. Implementation of these devices also provides great economic benefits to industry by offering better asset tracking performance and reducing overall product handling time (Burch et al., 2016a). Additionally, these devices offer comparatively lower total cost of ownership due to their longer deployment lifecycles even though initial investment for purchasing these devices is significantly higher than standard commercial equipment (Gooley, 2012; Wright, 2017). This large, initial purchasing investment requirement makes device choice and the overall decision-making process critical for any company planning to deploy new technology solutions on this scale. In this article, a well-structured methodology for selecting an appropriate ruggedized handheld device is proposed to aid this complex decision-making process in a robust way with lower uncertainty while meeting both economic, macro-ergonomic (the management component of the cultural subsystem), and human factors considerations.
Location-based monitoring in production environments: does transparency help to increase the acceptance of monitoring?

Advances in technology such as intelligent surveillance give organizations with a constant overview of the business process by collecting various data that help to coordinate, plan and optimize production processes (Brettel et al., 2014). Location-based services are defined as services that take an entity’s geographic location into account (Junglas & Watson, 2008). The tracking and tracing of physical objects is referred to as asset tracking and captures all activities and methods for capturing and using real-time locations and status data for objects, such as tools, containers, raw materials or production orders. It is already standard in many industries (Oztekin et al., 2010).
Digital technology enablers and their implications for supply chain management
Published in Supply Chain Forum: An International Journal, 2020
RFID uses single-chip radios and provides the tagging of physical objects – people, places, and things so they can interface with computers. RFID can provide more information than bar-coding. This information can be used to improve inventory management at the retail store and along the supply chain. RFID can revolutionise the way the supply chain meets customer expectations by offering direct insight into consumers’ buying habits and increasing efficiency and accuracy within the supply. The technology could dramatically improve supply chain performance by reducing inventory levels, lead times, stock- outs, and shrinkage rates. It can also increase throughput, inventory visibility, inventory record accuracy, order accuracy, customer service, quality, and collaboration among supply chain members (Attaran 2012). In general, RFID technology could generate business value at three levels for any SCM: Immediate: RFID readers can read multiple tags simultaneously, without requiring line of sight or human involvement. This can cut checkout, inventory control, and loss prevention costs.Short-Term: RFID can improve supply chain performance through asset tracking, product origin tracing, and product recall.Long -Term: Collaborative use of RFID information can help supply chain partners put the right item in the right place at the right time and for the right price. And demand-driven, product fulfilment systems can link consumer behaviour back into inventory planning and logistics.
