A critical analysis of research potential, challenges and future directives in industrial wireless sensor networks

In recent years, Industrial Wireless Sensor Networks (IWSNs) have emerged as an important research theme with applications spanning a wide range of industries including automation, monitoring, process control, feedback systems and automotive. Wide scope of IWSNs applications ranging from small production units, large oil and gas industries to nuclear fission control, enables a fast-paced research in this field. Though IWSNs offer advantages of low cost, flexibility, scalability, self-healing, easy deployment and reformation, yet they pose certain limitations on available potential and introduce challenges on multiple fronts due to their susceptibility to highly complex and uncertain industrial environments. In this paper a detailed discussion on design objectives, challenges and solutions, for IWSNs, are presented. A careful evaluation of industrial systems, deadlines and possible hazards in industrial atmosphere are discussed. The paper also presents a thorough review of the existing standards and industrial protocols and gives a critical evaluation of potential of these standards and protocols along with a detailed discussion on available hardware platforms, specific industrial energy harvesting techniques and their capabilities. The paper lists main service providers for IWSNs solutions and gives insight of future trends and research gaps in the field of IWSNs

Information Centric Networking in the IoT: Experiments with NDN in the Wild

This paper explores the feasibility, advantages, and challenges of an ICN-based approach in the Internet of Things. We report on the first NDN experiments in a life-size IoT deployment, spread over tens of rooms on several floors of a building. Based on the insights gained with these experiments, the paper analyses the shortcomings of CCN applied to IoT. Several interoperable CCN enhancements are then proposed and evaluated. We significantly decreased control traffic (i.e., interest messages) and leverage data path and caching to match IoT requirements in terms of energy and bandwidth constraints. Our optimizations increase content availability in case of IoT nodes with intermittent activity. This paper also provides the first experimental comparison of CCN with the common IoT standards 6LoWPAN/RPL/UDP.Comment: 10 pages, 10 figures and tables, ACM ICN-2014 conferenc

PhyNetLab: An IoT-Based Warehouse Testbed

Future warehouses will be made of modular embedded entities with communication ability and energy aware operation attached to the traditional materials handling and warehousing objects. This advancement is mainly to fulfill the flexibility and scalability needs of the emerging warehouses. However, it leads to a new layer of complexity during development and evaluation of such systems due to the multidisciplinarity in logistics, embedded systems, and wireless communications. Although each discipline provides theoretical approaches and simulations for these tasks, many issues are often discovered in a real deployment of the full system. In this paper we introduce PhyNetLab as a real scale warehouse testbed made of cyber physical objects (PhyNodes) developed for this type of application. The presented platform provides a possibility to check the industrial requirement of an IoT-based warehouse in addition to the typical wireless sensor networks tests. We describe the hardware and software components of the nodes in addition to the overall structure of the testbed. Finally, we will demonstrate the advantages of the testbed by evaluating the performance of the ETSI compliant radio channel access procedure for an IoT warehouse

Intellectual Property and Innovation: Changing Perspectives in the Indian IT Industry

Indian government has undertaken significant modifications in the IP regime of the country. This will lead to a realignment of business strategies by firms in several sectors. Similarly, with liberalization and globalization, new opportunities for IP creation may emerge for Indian firms. In this context, the paper attempts to document the emerging perspectives vis-�-vis IPRs in the Indian IT industry and explore factors that are driving the change in perspectives. Large IT firms and firms in high-end niche areas are proactively seeking IP based growth strategies. While they typically seek IP protection in Western nations and not so much in India, this has led them to perceive restrictive IP regimes more positively. IP regimes in the West are more relevant for IP creating Indian IT firms today but this may change in the near future as Indian market expands. Significant IP creation by MNC subsidiaries in India is also contributing to this change in perception. Survey data show that an average IT firm in India also perceives IP protection as an important appropriability mechanism, but access to markets and relevant complementary assets continue to be more important for appropriating profits from their economic activity. A positive view of the restrictive IP regimes also gets reflected in the demands of Indian industry associations for changes in the Indian law. Broadly, these changes in perceptions seem to be linked to the evolving global production networks, changing activity profile of Indian IT firms, emerging business opportunities and changes in the competitive scenario. The understanding of Indian IT firms of the complexities of IP regimes remains rudimentary and they will need significant preparation to deal with these IP related challenges.
