Load balancing and energy conservation techniques are one of the important constraints in the design of in wireless sensor network (WSN). Usually, clustering technique helps the network in the minimum utilization of energy that results in enhancing network lifetime. Moreover, various nodes in the multihop network that are near to the base station drain their battery very quickly thus result in creating...
Home Automation Systems have been continuously evolving in the past few years: some of the systems are focusing their attention on providing remote access and control of the system, while others are more focused on the interconnectivity of the devices and on integrating them into greater systems, like smart cities. In this paper we propose a hierarchical architecture for Home Automation Systems, which...
The challenges to deal with to design a WSN node which can be used in safety-relevant application are, to the present day, still to be completely investigated and solved. Nevertheless, a prototype implementation is presented in this paper, with an emphasis on the chosen hardware architecture and components, highlighting the limitations imposed by specific choices. Furthermore, an example application...
The wireless sensor network (WSN) represent a fertile area for research and exploration, especially with the enormous development in modern electronic systems, where it becomes an alternative to traditional wired systems. The wireless systems are less energy-consumptive and inexpensive, in addition, it helps to reduce the complexity of wiring. Wireless sensor networks require the design of high density...
In this paper, we are presenting a data flow and fault management architecture, developed for an event driven wireless sensor network used in landslide surveillance. Our concept system collects landslide data using a dedicated wireless sensor network. The WSN was configured with tree architecture and contains one gateway, relay nodes, and multiple end nodes. The WSN components were distributed in...
The paper deals with the verification of reconfigurable real-time systems to be validated by using the Object Constraint Language (abbrev, OCL). A reconfiguration scenario is assumed to be any adaptation of the execution to the system environment according to user requirements. Nevertheless, since several behaviors can be redundant from an execution to another, the use of OCL is insufficient to specify...
Wireless sensor networks (WSN) play an important role in many applications like healthcare, traffic monitoring, security, environmental and infrastructure monitoring. When designing these applications for different domains like healthcare, traffic management or military intelligence, people face a lot of challenges. Service-oriented architecture (SOA) is an emerging area in distributed computing that...
Many industrial application could benefit from the use of wireless sensor networks technology in safety critical context.

Wireless Sensor Networks have been used for many applications especially for sites monitoring and surveillance. This contribution proposes a new grid-based architecture to monitor an area of interest that could be of a large size through a number of energy efficient sensors deployed randomly to cover the whole area. The proposed solution relays on a grid-based scheme where the monitored area is logically...
Wireless Sensor Networks (WSNs) are constrained by a limited energy sources. Trust in a WSN is defined as the amount of confidence obtained from the individual node with respect to its data collecting, composing and communication (C3) probability with other peered nodes. Trustworthiness and energy optimization of Wireless Sensor Networks (WSNs) is an active research topic. Trustworthiness of a WSN...
This paper presents the design and implementation of an integrated architecture for key exchange and authentication in wireless sensor networks (WSNs) employing elliptic curve cryptography (ECC) for key management. Instead of implementing a standard algorithm such as SHA or AES for authentication, this paper considers an elliptic curve based message authentication code (MAC) for optimized design of...
