In Wireless Sensor Network (WSN) energy is the main concern while designing a WSN protocol. Clustering is one of the process to minimize the energy consumption in WSN. Local election of clustering head (CH) requires many communications such as hello message, advertising their chances and fuzzy logic process requires many CPU cycles, high power microcontrollers, high capacity of memories which increase...
The use of hierarchical structure in a wireless sensor network such as the Smart Grid can significantly improve monitoring networks through the use of data aggregation techniques. This reduces the processing at the central server as well as allowing for localized processing and decision-making at the nodes. However, existing routing protocols such as LEACH suffer from limited support for upstream...
The technological developments has been focus towards the use of smart grids, as it is know the future of the distribution systems of electric power. In this document, it is presented the elements that are necessary to build an infrastructure of measurement on micro grids by using wireless sensors; the recovery of the information measured from the microgrid requires an infrastructure that fulfill...
In wireless Sensor Networks (WSNs), node placement plays a significant role to meet design goals such as cost effectiveness, connectivity, lifetime, and data latency. In this paper, we propose a new algorithm to assist in the placement of nodes for a WSN who monitors an underground tunnel infrastructure. To improve WSN's nodes utilization rate, we defines a minimization problem of distances between...
The Kingdom of Saudi Arabia, like many other Gulf Council Countries, is lately experiencing a very rapid population and industrial growth, which results in an increasing demand for energy. To meet this growing demand, the GCC too is transitioning towards a smarter electricity grid with increased penetration of renewable sources. However, all agree that the success of such a shift in paradigm also...
We address the problem of providing users, namely non specialists, with out-of-the-box, programmable, Wireless Sensor-Actuator Networks (WSN). The idea is that users get a package containing a gateway and an undetermined number of nodes, pre-configured to work as a self-organized wireless mesh. Each node comes with two pre-installed components: a small operating system and a virtual machine. The user...
The present era of wireless communication system has witnessed a maximized score of interest in adopting a specialized branch called as Wireless Sensor Network. Although, the research on the concept is more than a decade old, still WSN is shrouded by various types of operational loopholes, which decreases the technical adoption of the commercial practices of the protocols. The proposed paper has addressed...
Research institutes and companies are focusing intensively on Complex Event Processing, Event Stream Processing, Information Flow Processing and Surprise Event Detection methods and algorithms. This phenomenon is intensified by the rapid evolution and spreading in practice of the Internet of Things services. A huge amount of data is created continuously by the physical and logical sensors embedded...
In this work it is described the progresses carried out in the implementation of a wireless sensor network for seismic monitoring with possibility of access to the Internet via modem GSM/GPRS. The network is designed to minimize implementation and localization costs in order to deploy a large number of sensors in mesh topology in areas covering the civil structure to be monitored.
During the past decade, Wireless Sensor Networks (WSN) has been enormously used in various fields such as military, environmental and traffic monitoring, home monitoring, medical, space and undersea exploration. These applications require deployment of sensors which detect or sense data from environment and relay this information to the base station or central unit. The sensors operate autonomously...
Coverage and connectivity are two important performance evaluation indices for wireless sensor network (WSNs). In this paper, we focus on the connected target k-coverage (CTCk) problem in heterogeneous wireless sensor networks (HWSNs). A distributed connected target k-coverage algorithm (DCTCk) is proposed in order to generate connected cover sets for energy efficient connectivity and coverage maintenance...
In this paper, a novel spectrum handoff scheme for cognitive ultra-wide band industrial networks (CUWBINs) is proposed, where secondary users (SUs) can access the licensed channels despite the present of primary users' signals. To maintain continuous connectivity between the cognitive users, licensed channels can be opportunistically used by an SU as long as its transmission does not interfere with...
Recent studies show that the novel wireless charging technology can extend the lifetime of Wireless Sensor Networks (WSNs) towards perpetual operations.

Linear programming, genetic algorithms and other optimization methods are used on disjoint set covers to maximize the lifetime. This paper provided a genetic algorithm-based secluding method to generate the solution with the maximum possible lifetime...
Nowadays communication and data transmission among various heterogeneous networks is growing speedily and drastically. More number of heterogeneous networks are created and deployed by government as well as by private firms. Due to the distance, mobility, behavior of nodes in the networks and dynamic in nature, it is essential to provide security for all the networks separately or distributed. Various...
In the field of wireless industrial automation networks (WIANs), the WirelessHART and ISA100.11a protocols are promoted, which support time division and carriersensing multiple access schemes, channel hopping schemes, and mesh network topology to improve reliability and scalability. However, they work on the 2.4-GHz non-licensed industrial, scientific, and medical (ISM) frequency band. This band has...
This article presents a new platform independent approach to the real-time solution of inverse problems on embedded systems. The class of problems addressed corresponds to ordinary differential equations (ODEs) with generalized linear constraints, whereby the data from an array of sensors forms the forcing function. The algebraic discretization of the problem enables an one-to-one mapping of the ODE...
To track and detect continuous natured objects in wireless sensor networks, large number of sensor nodes are involved. These continuous objects like bio-chemical diffusions, forest fires, oil spills usually spread over larger area. Phenomena sensing nodes need to communicate with each other for information exchange and also send sensing information to sink, possibly by passing through many intermediate...
An important aspect of Wireless Sensor Network (WSN) operation is identifying the physical location of each sensor in 3-D space — a process known as localization where an anchor with known location determines the location of other location-blind nodes. In this paper, we present a detailed performance analysis of three scenarios: (1) localization of blind nodes using an airborne mobile anchor; (2)...
