With the help of this paper we come to know that need for accurate time synchronization in the order of 0.6 − 9 μs every few minutes is necessary for data collection and analysis. Two-stage energy-efficient time synchronization is proposed in this paper. Firstly, the network is divided into clusters and a head node is elected using Low-Energy Adaptive Clustering Hierarchy based algorithm. Later, multiple packets of different lengths are used to estimate the delay between the elected head and the entire network hierarchically at different levels Wireless sensor networks (WSNs) have not only become an attractive solution for low power implementations and embedded systems but also for the Power transmission and distribution.

Wireless Sensor Networks (WSNs) are applicable in numerous domains, including industrial automation where WSNs may be used for monitoring and control of industrial plants and equipment. However, the requirements in the industrial systems differ from the general WSN requirements. In recent years, standards have been defined by several industrial alliances. These standards are specified as frameworks with modifiable parts that can be defined based on the particular application of WSN. However, limited work has been done on defining industryspecific protocols that could be used as a part of these standards. In this survey, we discuss representative protocols that meet some of the requirements of the industrial applications. Since the industrial applications domain in itself is a vast area, we divide them into classes with similar requirements. We discuss these industrial classes, set of common requirements and various stateof-the-art WSN standards proposed to satisfy these requirements. We then present a broader view towards the WSN solution by discussing important functions like medium access control, routing, and transport in detail to give some insight into specific requirements and the classification of protocols based on certain factors. We list and discuss representative protocols for each of these functions that address requirements defined in the industrial classes. Security function is discussed in brief, mainly in relation to industrial standards. Finally, we identify unsolved challenges that are encountered during design of protocols and standards. In addition some new challenges are introduced and discussed.

Industrial Wireless Sensor Networks (ISWN): Requirements and Solutions
Industrial Wireless Sensor Networks (IWSN) are preferred over bulky wired networks in industrial monitoring and automation. These sensors are used to access locations, which are technically unreachable. The use of IWSN not only reduced the cost of automation systems but also played a significant role in alarm management by real time data transfer. ZigBee and WirelessHART are already deployed protocols for IWSN. ISA100.11a developed by International Society of Automation was specially designed for IWSN. The main features of this standard are low power consumption, real time fast data transfer, scalability, security, reliability, coexistence with other network architectures and robustness in harsh industrial environments. To achieve these features, these protocols use layer structure, which provides security, fast and reliable data transfer. IEEE 802.15.4 is used at its physical layer with variable data slots. This paper presents the results of the simulation of ISA100 done on Pymote ...
Future Internet, 2010
Wireless Sensor Networks (WSNs) are gradually adopted in the industrial world due to their advantages over wired networks. In addition to saving cabling costs, WSNs widen the realm of environments feasible for monitoring. They thus add sensing and acting capabilities to objects in the physical world and allow for communication among these objects or with services in the future Internet. However, the acceptance of WSNs by the industrial automation community is impeded by open issues, such as security guarantees and provision of Quality of Service (QoS). To examine both of these perspectives, we select and survey relevant WSN technologies dedicated to industrial automation. We determine QoS requirements and carry out a threat analysis, which act as basis of our evaluation of the current state-of-the-art. According to the results of this evaluation, we identify and discuss open research issues.

Survey and systematic mapping of industrial Wireless Sensor Networks
Journal of Network and Computer Applications, 2017
The Wireless Sensor Network (WSN) is an infrastructure comprised of sensing, computing, and communication devices, that obtain and process data to help understand the behavior of the monitored environment, and to react to events and phenomena that occur in it. The WSN can be used in domains such as agriculture, energy, industrial automation, medical health care, smart building, and so on. In industry, the characteristics of the wireless channel are different in comparison to other WSN environments, such as home and office environments. The use of WSN in industry is subject to typical problems of wireless communications, such as noise, shadowing, multipath fading and interference. In addition, the wireless channel in many industrial environments is non-stationary for a long term, which can cause abrupt changes in the characteristics of the channel over time. A set of standards was developed for industrial WSN, to overcome these limitations, such as WirelessHART, ISA100.11a, WIA-PA, and IEEE 802.15.4e. All the mentioned standards are based on the IEEE 802.15.4 physical layer, but define different mechanisms for the upper layers. However, according to recent publications, problems still can arise in the deployment of networks that follow the standards, because of multipath effects, and interference. This survey provides a structured overview of the standards used to implement industrial WSN, their advantages and drawbacks, and discusses the characteristics of the wireless channel in industrial environments. Finally, a systematic mapping is described, that presents results of publications about industrial WSN, and highlights important topics to be studied in this field.
