The network of nodes with sensing technology and wireless capability is termed as Wireless Sensor Network (WSN). WSN has high potential to adapt to the changes of how we live. Its budding technology makes the motes communicate with each other efficiently. The sensor nodes in WSN are referred as motes and they form the main building blocks for creating a network. The motes need to work efficiently...
The popularity of wireless communication application is increased specially in the ISM band which provides services for free. Bluetooth is one of the technology in unlicensed band which becomes very useful now a days in many short rage application because of its advantages like low power consumption, low cost, low size, universal applicability, multiple simultaneous link. This paper is on the one...
The research area of Wireless Sensor Networks (WSN) is growing rapidly. WSN technology is making entrance into new application areas, for example industrial control and Critical Infrastructure (CI) environments. Energy efficiency is a highly prioritized goal of communication protocols and application design for WSN. However, the usage of WSN in both industrial and CI environments are starting to require...
This paper presents a SystemC-based system-level modeling framework for wireless sensor networks. Benefit from the advantages of SystemC in the aspect of hardware and software co-simulation, this modeling framework allows the performance evaluation of sensor networks at system-level with elaborate sensor node models. It is used to study an industrial application, in which an IEEE 802.15.4 sensor network...
Wireless Sensor Networks (WSNs) have been widely discussed in many applications. But a key design challenge is to solve power consumption, the reliability of radio communication and self-organizing of network. This paper proposes a design scheme of wireless sensor networks node architecture, builds a computer monitoring platform for experimenting with several of these nodes and designs a flexible...
This paper describes the modeling of a microsensor node dedicated to wireless sensor network applications. The definition of the different node modes is first introduced: wake-up, measure, processing, transmission, reception and sleep. Then, contrary to the literature, a complete sensor node energy model is derived and used to analyze node autonomy. This model allows to estimate the part of each element...
Wireless sensor node (WSN) lifetime is correlated with the battery current usage profile. State of the art in wireless sensor nodes current consumption shows that available models have not been extensively tested and experimentally validated. This work aims to seek answers to the following questions: is it accurate the node lifetime prediction obtained with available models? Moreover, is the radio...
The concept of simple sensor nets, devices the size of ping-pong balls, sprinkled liberally on the ground, has been around for a long time. Some of the big challenges have always been cost and complexity, as well as power consumption. While there have been a plurality of proprietary wireless systems developed over the past decade or so for application to this problem, these systems have suffered from...
