In underwater sensor networks (UWSNs), information transmission is extremely challenging because of the underwater channel. Underwater acoustic channel suffers from long propagation delay and low bandwidth is inclined to packet losses. Hence, the design of an energy efficient communication system is challenging under the water. In this paper, we present an energy efficient clustered multi-hop routing...
In the recent year's low power computing systems have gained popularity. Networks, which use low power computer systems and transmitted data by using wireless connection are called wireless sensor networks. Nowadays, the most topical researches pertaining to wireless sensor networks are grounded on the new optimization of structure of network transmission protocol, the routing optimization in transmission...
The present paper allows to energy information collecting agent for IoT BigData system. Energy management system (EMS) is computer-based platform to monitor and control energy usage at a smart home and building. There are several model EMS — centralized and distributed. This paper suggested hybrid architecture of EMS for efficiently energy management.
Smart metering is one of the main objectives for the EU member states to ensure the benefit of consumers on the long term. Due to its functionality, smart meters have a wide applicability in: power quality monitoring, energy savings, data awareness and fraud detection. With long-term cost benefits of the smart meters, it is expected that 72% of European consumers will have a smart meter for electricity...
One of the most well-known clustering methods for wireless sensor network is, no doubt, the so-called low energy adaptive clustering hierarchy (LEACH) because it is simple and easy to implement. Although LEACH tries to provide a fair selection mechanism by randomly selecting a number of sensors as the cluster-heads, it does not take into account the distribution of sensors, the main reason that LEACH...
This paper describes a prototype implementation of a wireless sensor network allowing for the application of the Industry 4.0. concept. It discusses both the requirements for wireless sensor networks for industrial applications as well as ways of their development. Operating modes of wireless sensor network elements enabling implementation of the indicated requirements are described in detail. Authors...
Recently, cooperative communication has been used as a cost effective alternative to traditional MIMO systems. Even though cooperative relaying at the physical and/or MAC layer improves the performance of the network, it increases the level of interference in a multihop wireless network. In a multihop wireless adhoc network, the amount of interference created can be reduced by using power control...
The Internet of Things (IoT) offers challenges that are being met by the convergence of multiple technologies, which have matured rapidly over the past decade. Broadband communication and mobile platforms enable raw data collection and its transmission to the cloud. Data science, e.g., deep learning, transforms large amounts of data from the Internet-connected sensors and personal devices in meaningful...
The use of animals, specially ovines, for controlling infesting species in crops is an ancient method that has several advantages with respect to the use of chemical and/or mechanical techniques. Shepherds required to supervise animals, are getting increasingly less available and are costly. Over the last years, technologies for automatic animal supervision have been investigated, typically including...
Several monitoring oriented applications in Wireless Sensor Networks (WSNs) are characterized by the necessity of two data-reporting modes: time-driven and event-driven. The former is used mainly for constantly supervising an area and the latter for event detection and target tracking. By switching between both modes a WSN can improve its energy-efficiency and accuracy of measurement processes, compared...
Consider the problem of energy loss caused by inefficient use of energy in Wireless Sensor Networks (WSN).

Firstly, use the distributed cluster computing energy-efficient routing scheme (DCCERS) to select cluster heads according to the center of gravity and...
In the Internet of Things (IoT) environment, a sensor network protocol must satisfy various application--specific requirements such as synchronous, asynchronous, symmetric, and asymmetric operations. Most block design--based neighbor discoveryprotocolscan not support asymmetricoperations.In this paper, we propose a new block cycle length--based asymmetric rendezvous protocol for neighbor discovery...
