Wireless Sensor Networks are used to perform distributed sensing in various fields, such as health, military, home etc. Sensing is done in order to have a better understanding of the behavior of the monitored entity or to monitor an environment for the occurrence of a set of possible events, so that proper action may be taken whenever necessary. In, wireless sensor networks, sensor nodes should communicate...
Cloud computing seems to be the new paradigm platform where data owner can not only remotely store their data, but also require service provision attributed with ubiquity, reliability, high-performance, efficiency, and scalability. But applying these cloud advantages on huge sensed data which contains sensitive information implies critical data security issues. Because, this new vision service: ‘Cloud...
Nowadays visual sensor networks are used in emergency or time of surveillance of remote area where human reach is not possible. There situations arise when mobility of nodes is required in visual sensor network. In this paper we considers mobility of visual sensor nodes and tries to maximize the lifetime of network using priority if nodes. We use hierarchical and heterogeneous architecture for deploying...
Wireless sensor networks (WSN's) have become the part and parcel of our life. The Wireless sensor networks are used to sense and process data in applications like Water Level Monitoring, Vehicle Tracking and Patient Health care Monitoring systems. The energy is supplied to the sensor node through the battery. As the battery storage cannot be retained for longer time, the sample of information may...
Nowadays Sensor-cloud has received a lot of interests among researchers in the field of Wireless Sensor Networks (WSN) as well as Cloud Computing. An integral part of the Sensor Cloud platform is the Collaboration of WSN providers which improves the utilization of sensor resources. The physical sensors in such a collaborative environment are shared among multiple applications from different administrative...
In recent years, an increasing number of researchers have become involved in wireless sensor networks (WSNs) and cloud computing. However, integrating WSN and cloud computing technology to monitor the environment is still an open issue. In this paper, we propose a mobile-device-based environmental monitor based on SaaS (Software as a Service) of cloud computing architecture. The proposed model is...
Designing Wireless Sensor Networks (WSN) is tedious and time consuming process, especially WSN adoption for real-world operation. To decrease WSN design iteration count, from idea to real-world operation, specific tools must be designed. Providing end-users: with simplified WSN design procedure; with detailed information from all system layers (low to high). In this work we propose - EDI Testbed WSN...
Wireless sensor network (WSN) testbed design challenges can be divided into three main sub-categories: architectural, hardware and software. By considering all these challenges, an optimal solution was found and EDI TestBed created. In this paper, a method, which solves software related problems in large scale WSN testbed, such as how to distribute computational resources, control all of the testbed...
Wireless sensors networks (WSNs) became a successful alternative to cabled systems used for surveillance or monitoring, allowing more freedom to patients or elderly persons and also lower costs for implementation improving the quality of medical care. The paper presents a possible solution for a surveillance system based on a BeagleBoard-XM card, connected to a video camera and emulates the data provided...
Wireless Sensor Networks (WSNs) are a key technology for future social and industrial developments. With increasingly complex applications, the compute demands for in-node / in-network processing have been growing steadily, while the capabilities of energy-harvesting or -storage systems have advanced only slowly. We present the Hardware-Accelerated Low Power Mote (HaLoMote), a heterogeneous system...
The Internet-of-Things (IoT) envisions a world where billions of everyday objects and mobile devices communicate using a large number of interconnected wired and wireless networks. Maximizing the utilization of this paradigm requires fine-grained QoS support for differentiated application requirements, context-aware semantic information retrieval, and quick and easy deployment of resources, among...
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...

The architecture of proposed network works with the Floodlight controller, which executes the module of load balance, modified to be employed at dependency on the...
The Deterministic Networking paradigm, which is prevalent in Operational Technology (OT), is now getting traction at the IETF and the IEEE, to enable the convergence of OT with Information Technology (IT), and the Industrial Internet vision, whereby the automation world can leverage IT technology to optimize OT processes. New Working Groups (WGs) are now emerging at the IETF to develop new routing...
Limited resources (such as energy, computing power, storage, and so on) make it impractical for wireless sensor networks (WSNs) to deploy traditional security schemes. In this paper, a hierarchical key management scheme is proposed on the basis of identity-based encryption (IBE). This proposed scheme not only converts the distributed flat architecture of the WSNs to a hierarchical architecture for...
Wireless Sensor Networks (WSNs) have been widely considered as a promising solution to support different types of applications on industrial environments. Many of these applications impose strict dependability requirements, since a system failure may result in economic losses, or damage for human life or to the environment. The absence of an effective approach enabling the dependability evaluation...
This paper mainly focuses on performances optimization and analysis of micro power ring oscillator for energy scavenging applications in wireless sensor networks. A novel method of optimizing electrical performances (power, frequency) and geometry (transistors sizing) for CMOS ring oscillators is presented using the contour Graph method.

6LoWPAN (IPv6 over Low Power Wireless Personal Area Networks) is gaining more and more attraction for the seamless connectivity of embedded devices for the Internet of Things (IoT). Whereas the lower layers (IEEE802.15.4 and 6LoWPAN) are already well defined and consolidated with regard to frame formats, header compression, routing protocols and commissioning procedures, there is still an abundant...
