Recent advances in industrial wireless sensor networks towards efficient management in IoT

With the accelerated development of Internet-of- Things (IoT), wireless sensor networks (WSN) are gaining importance in the continued advancement of information and communication technologies, and have been connected and integrated with Internet in vast industrial applications. However, given the fact that most wireless sensor devices are resource constrained and operate on batteries, the communication overhead and power consumption are therefore important issues for wireless sensor networks design. In order to efficiently manage these wireless sensor devices in a unified manner, the industrial authorities should be able to provide a network infrastructure supporting various WSN applications and services that facilitate the management of sensor-equipped real-world entities. This paper presents an overview of industrial ecosystem, technical architecture, industrial device management standards and our latest research activity in developing a WSN management system. The key approach to enable efficient and reliable management of WSN within such an infrastructure is a cross layer design of lightweight and cloud-based RESTful web service

The advancement in the wireless communications and electronics has led to the growth of low-cost sensor networks. Due to which the sensor networks is part of different application areas now. Low-cost, low-power and multifunctional small-sized sensor devices are the great end-products of wireless sensor network technologies. These sensor nodes together in a group form a sensing network. A sensor network can offer access to data anytime, anywhere by gathering, processing, evaluating and distributing data. The evolution of information sending in wireless sensor networks is boosting to devise newer and more advanced routing strategies. Many strategies have considered data collection and data dissemination. In this project, the data produced by the sensor nodes is aggregated and provide the further guaranteed data transmission to sink node/ base station using clustering mechanism and node concentration with SPIN protocol. The proposed scheme provides increased network lifetime, better data gathering and period of stability as compared to M-LEACH protocol

An Approach to Select Cluster Head in Wireless Sensor Networks

Recent advancement in mobile network and wireless technologies has resulted in improvements in sensor networks. But there are various challenges and security threats that disturb the Wireless communication. This paper proposes a technique called cluster head selection, which is used for selecting the cluster head. The longevity of a network can be enhanced by using a group of mobile sensor network. The role of the head of this group is collecting data and forwarding it. This data is transferred to the head by the other nodes in the group. We are using fuzzy logic scheme for selecting cluster head. AOMDV protocol is used for path identification in sensor network

No-Sense: Sense with Dormant Sensors

Wireless sensor networks (WSNs) have enabled continuous monitoring of an area of interest (body, room, region, etc.) while eliminating expensive wired infrastructure. Typically in such applications, wireless sensor nodes report the sensed values to a sink node, where the information is required for the end-user. WSNs also provide the flexibility to the end-user for choosing several parameters for the monitoring application. For example, placement of sensors, frequency of sensing and transmission of those sensed data. Over the years, the advancement in embedded technology has led to increased processing power and memory capacity of these battery powered devices. However, batteries can only supply limited energy, thus limiting the lifetime of the network. In order to prolong the lifetime of the deployment, various efforts have been made to improve the battery technologies and also reduce the energy consumption of the sensor node at various layers in the networking stack. Of all the operations in the network stack, wireless data transmission and reception have found to consume most of the energy. Hence many proposals found in the literature target reducing them through intelligent schemes like power control, reducing retransmissions, etc. In this article we propose a new framework called Virtual Sensing Framework (VSF), which aims to sufficiently satisfy application requirements while conserving energy at the sensor nodes.Comment: Accepted for publication in IEEE Twentieth National Conference on Communications (NCC-2014
