Wireless communication, identification and sensing technologies enabling integrated logistics: a study in the harbor environment

In the last decade, integrated logistics has become an important challenge in the development of wireless communication, identification and sensing technology, due to the growing complexity of logistics processes and the increasing demand for adapting systems to new requirements. The advancement of wireless technology provides a wide range of options for the maritime container terminals. Electronic devices employed in container terminals reduce the manual effort, facilitating timely information flow and enhancing control and quality of service and decision made. In this paper, we examine the technology that can be used to support integration in harbor's logistics. In the literature, most systems have been developed to address specific needs of particular harbors, but a systematic study is missing. The purpose is to provide an overview to the reader about which technology of integrated logistics can be implemented and what remains to be addressed in the future

The Emerging Internet of Things Marketplace From an Industrial Perspective: A Survey

The Internet of Things (IoT) is a dynamic global information network consisting of internet-connected objects, such as Radio-frequency identification (RFIDs), sensors, actuators, as well as other instruments and smart appliances that are becoming an integral component of the future internet. Over the last decade, we have seen a large number of the IoT solutions developed by start-ups, small and medium enterprises, large corporations, academic research institutes (such as universities), and private and public research organisations making their way into the market. In this paper, we survey over one hundred IoT smart solutions in the marketplace and examine them closely in order to identify the technologies used, functionalities, and applications. More importantly, we identify the trends, opportunities and open challenges in the industry-based the IoT solutions. Based on the application domain, we classify and discuss these solutions under five different categories: smart wearable, smart home, smart, city, smart environment, and smart enterprise. This survey is intended to serve as a guideline and conceptual framework for future research in the IoT and to motivate and inspire further developments. It also provides a systematic exploration of existing research and suggests a number of potentially significant research directions.Comment: IEEE Transactions on Emerging Topics in Computing 201

Strategically Addressing the Latest Challenges of Workplace Mobility to Meet the Increasing Mobile Usage Demands

During this post-PC era, many organizations are embracing the concept of IT consumerization/ Bring-Your-Own Device (BYOD) in their workplace. BYOD is a strategy that enables employees to utilize their personally-owned mobile devices, such as smart phones, tablets, laptops, and netbooks, to connect to the corporate network and access enterprise data. It is estimated that employees will bring two to four Internet-capable devices to work for personal and professional activities. From increased employee satisfaction and productivity to lower IT equipment and operational expenditures, companies have recognized that mobile devices are reasonably essential to their own success. However, many organizations are facing significant challenges with the explosion of mobile devices being used today along with provisioning the appropriate supporting infrastructure due to the unprecedented demands on the wireless and network infrastructures. For example, there is not only a growth in the number of wirelessly connected devices but the amount of bandwidth being consumed on the enterprise networks as well which is furthermore driven by increased usage of video and enterprise applications. Managing mobility and storage along with securing corporate assets have become difficult tasks for IT professionals as many organizations underestimate the potential security and privacy risks of using wireless devices to access organizational resources and data. Therefore, to address the needs and requirements of a new mobile workforce, organizations must involve key members from the Information Technology (IT), Human Resources (HR) and various business units to evaluate the existing and emerging issues and risks posed by BYOD. Then a mobile strategy should be developed by taking into consideration the enterprise objectives to ensure it aligns with the overall organizational strategy. There are various solutions available to address the needs and demands of an organization, such as Distributed Intelligence Architecture, network optimization, monitoring tools, unified management and security platforms, and other security measures. By implementing a suitable mobile strategy, organizations can ensure their particular enterprise network and wireless architecture is designed for highly scalability, performance and reliability. They must also evaluate their existing policies and procedures to ensure appropriate security and privacy measures are in place to address the increasing mobile usage demands and potential liability risks. By taking these factors into consideration, our team has analyzed the current BYOD issues for Educational Testing Service (ETS), which is a non-profit organization based in Princeton, New Jersey. Our findings have revealed a few major technical concerns relating to inadequate network and wireless infrastructure and the lack of a unified management and security platform. Thus, the team has recommended for ETS to implement Distributed Intelligence Architecture, network optimization and Enterprise Mobility Management (EMM) to address and resolve their current issues and risks. In conclusion, companies are beginning to seize this transition in order to become competitive and productive in the workplace; however the unprecedented demands on the corporate network and risk to data security are critical aspects that need to be evaluated on an on-going basis. With this analysis, organizations can review, evaluate and implement the proposed solutions and best practices to address the most common BYOD-related issues that companies are facing these days. However, organizations should continually research the latest technologies that may be available and implement solutions that specifically meet their issues

Economic Experiments and Neutrality in Internet Access

Economic experiments yield lessons to firms that can be acquired only through market experience. Economic experiments cannot take place in a laboratory; scientists, engineers, or marketing executives cannot distill equivalent lessons from simply building a prototype or interviewing potential customers and vendors. The historical record illustrates that economic experiments were important for value creation in Internet access markets. In general, industry-wide returns from economic experiments exceed private returns, with several important exceptions. Those conclusions motivate an inquiry into whether regulatory policy can play a role in fostering the creation of value. The net neutrality debate is reinterpreted through this lens. A three part test is proposed for encouraging economic experiments from both broadband carriers and providers of complementary services.

Framework for integrated oil pipeline monitoring and incident mitigation systems

Wireless Sensor Nodes (motes) have witnessed rapid development in the last two decades. Though the design considerations for Wireless Sensor Networks (WSNs) have been widely discussed in the literature, limited investigation has been done for their application in pipeline surveillance. Given the increasing number of pipeline incidents across the globe, there is an urgent need for innovative and effective solutions for deterring the incessant pipeline incidents and attacks. WSN pose as a suitable candidate for such solutions, since they can be used to measure, detect and provide actionable information on pipeline physical characteristics such as temperature, pressure, video, oil and gas motion and environmental parameters. This paper presents specifications of motes for pipeline surveillance based on integrated systems architecture. The proposed architecture utilizes a Multi-Agent System (MAS) for the realization of an Integrated Oil Pipeline Monitoring and Incident Mitigation System (IOPMIMS) that can effectively monitor and provide actionable information for pipelines. The requirements and components of motes, different threats to pipelines and ways of detecting such threats presented in this paper will enable better deployment of pipeline surveillance systems for incident mitigation. It was identified that the shortcomings of the existing wireless sensor nodes as regards their application to pipeline surveillance are not effective for surveillance systems. The resulting specifications provide a framework for designing a cost-effective system, cognizant of the design considerations for wireless sensor motes used in pipeline surveillance

Leveraging Resources on Anonymous Mobile Edge Nodes

Smart devices have become an essential component in the life of mankind. The quick rise of smartphones, IoTs, and wearable devices enabled applications that were not possible few years ago, e.g., health monitoring and online banking. Meanwhile, smart sensing laid the infrastructure for smart homes and smart cities. The intrusive nature of smart devices granted access to huge amounts of raw data. Researchers seized the moment with complex algorithms and data models to process the data over the cloud and extract as much information as possible. However, the pace and amount of data generation, in addition to, networking protocols transmitting data to cloud servers failed short in touching more than 20% of what was generated on the edge of the network. On the other hand, smart devices carry a large set of resources, e.g., CPU, memory, and camera, that sit idle most of the time. Studies showed that for plenty of the time resources are either idle, e.g., sleeping and eating, or underutilized, e.g. inertial sensors during phone calls. These findings articulate a problem in processing large data sets, while having idle resources in the close proximity. In this dissertation, we propose harvesting underutilized edge resources then use them in processing the huge data generated, and currently wasted, through applications running at the edge of the network. We propose flipping the concept of cloud computing, instead of sending massive amounts of data for processing over the cloud, we distribute lightweight applications to process data on users\u27 smart devices. We envision this approach to enhance the network\u27s bandwidth, grant access to larger datasets, provide low latency responses, and more importantly involve up-to-date user\u27s contextual information in processing. However, such benefits come with a set of challenges: How to locate suitable resources? How to match resources with data providers? How to inform resources what to do? and When? How to orchestrate applications\u27 execution on multiple devices? and How to communicate between devices on the edge? Communication between devices at the edge has different parameters in terms of device mobility, topology, and data rate. Standard protocols, e.g., Wi-Fi or Bluetooth, were not designed for edge computing, hence, does not offer a perfect match. Edge computing requires a lightweight protocol that provides quick device discovery, decent data rate, and multicasting to devices in the proximity. Bluetooth features wide acceptance within the IoT community, however, the low data rate and unicast communication limits its use on the edge. Despite being the most suitable communication protocol for edge computing and unlike other protocols, Bluetooth has a closed source code that blocks lower layer in front of all forms of research study, enhancement, and customization. Hence, we offer an open source version of Bluetooth and then customize it for edge computing applications. In this dissertation, we propose Leveraging Resources on Anonymous Mobile Edge Nodes (LAMEN), a three-tier framework where edge devices are clustered by proximities. On having an application to execute, LAMEN clusters discover and allocate resources, share application\u27s executable with resources, and estimate incentives for each participating resource. In a cluster, a single head node, i.e., mediator, is responsible for resource discovery and allocation. Mediators orchestrate cluster resources and present them as a virtually large homogeneous resource. For example, two devices each offering either a camera or a speaker are presented outside the cluster as a single device with both camera and speaker, this can be extended to any combination of resources. Then, mediator handles applications\u27 distribution within a cluster as needed. Also, we provide a communication protocol that is customizable to the edge environment and application\u27s need. Pushing lightweight applications that end devices can execute over their locally generated data have the following benefits: First, avoid sharing user data with cloud server, which is a privacy concern for many of them; Second, introduce mediators as a local cloud controller closer to the edge; Third, hide the user\u27s identity behind mediators; and Finally, enhance bandwidth utilization by keeping raw data at the edge and transmitting processed information. Our evaluation shows an optimized resource lookup and application assignment schemes. In addition to, scalability in handling networks with large number of devices. In order to overcome the communication challenges, we provide an open source communication protocol that we customize for edge computing applications, however, it can be used beyond the scope of LAMEN. Finally, we present three applications to show how LAMEN enables various application domains on the edge of the network. In summary, we propose a framework to orchestrate underutilized resources at the edge of the network towards processing data that are generated in their proximity. Using the approaches explained later in the dissertation, we show how LAMEN enhances the performance of applications and enables a new set of applications that were not feasible
