TL;DR: This paper proposes new operating modes for BLE to provide a much wider applicability range covering asynchronous, aperiodic and very low frequency scenarios while extending lifetime, without modification of the existing BLE specification.
Abstract: Bluetooth Low Energy (BLE) has shown higher energy efficiency and robustness than other well known Wireless Sensor Network (WSN) protocols, making it a strong candidate for implementation in IoT scenarios. In addition, BLE is in almost every smartphone, turning it into perfect ubiquitous remote controls for smart homes, buildings or cities. In this paper we propose new operating modes for BLE to provide a much wider applicability range covering asynchronous, aperiodic and very low frequency scenarios while extending lifetime, without modification of the existing BLE specification. In order to estimate battery lifetime, we propose a coin cell battery model. We show how to efficiently adapt the protocol for different IoT scenarios based on their requirements, thus extending battery lifetime as much as possible while guaranteeing acceptable latency. Our results on two typical test-cases show that by using an optimized configuration and appropriate operating mode based on scenario requirements, lifetime can be increased up to ~2x (4.1 to 7.3 years) for a BLE master in a first case, and ~58x (3.05 months to 14.82 years) for a BLE slave in a second case. This shows BLE compatibility with a vast amount of IoT-related use cases.

TL;DR: The system provides for remote monitoring of the temperature and humidity levels of different parts of the plant with the help of the Wireless Senor Network Module by National Instruments and is based on labView software platform, which makes it ideal for industrial applications.
Abstract: Temperature and humidity are key issues to be taken care of in manufacturing plants and particularly that of electronic assemblies. Lack of control over any of them will not only affect the component and equipment but also the process and the operators' comfort, all ultimately leading to loss in production. This paper aims to provide a solution for similar problem. The system provides for remote monitoring of the temperature and humidity levels of different parts of the plant with the help of the Wireless Senor Network Module by National Instruments and is based on labView software platform. In addition, it has the functionalities of a secured access for login, easy reconfiguration, alarm facility in case of over limit and data logging capability for further analysis. All these make it ideal for industrial applications.

TL;DR: A WSN protocol named APTEEN protocol is proposed that helps to increase network lifetime of the nodes by periodic monitoring of the sensor nodes and communicating the necessary parameters to the farmers for taking action.
Abstract: In the recent years Wireless Sensor Networks (WSNs) have garnered attention. The applications of WSN includes collecting, storing and sharing sensed data which is used for habitat monitoring, agriculture, nuclear reactor control, security and tactical surveillance. Here we aim to explore the potential benefits of WSN to address precision agriculture problems in India. Since farming involves a vast area of land to be covered the deployment of sensor nodes includes a few barriers. Sensor nodes are battery powered and improvement of the lifetime of these nodes is important particularly when the nodes collect real time data and assist farmers towards proper cultivation. Here we propose a WSN protocol named APTEEN protocol that helps to increase network lifetime of the nodes by periodic monitoring of the sensor nodes and communicating the necessary parameters to the farmers for taking action. Cultivation of sugarcane crop includes a multi parameter monitoring system designed based on low-power ZigBee wireless communication technology for system automation and monitoring. Real time data is collected by wireless sensor nodes and transmitted to base station using zigbee. Data is received, saved and displayed at base station to achieve soil temperature, soil moisture and humidity monitoring. The data is continuously monitored at base station and if it exceeds the desired limit, a message is sent to farmer on mobile through GSM network for controlling actions. Further the limitations of wired sensor networks are overcome and have the advantage of flexible networking for monitoring equipment, convenient installation and removing of equipment, low cost and reliable nodes and high capacity.

Abstract: Afin d'accelerer ce processus de conception des systemes embarques, un environnement de simulation rapide et performant peut s'averer indispensable. Pour la rendre performante, les modeles comportementaux des composants elementaires du systeme doivent etre capables de remplacer les elements reels dans leurs influences et reponses a tous les phenomenes influents: perturbations, affaiblissements, retards... Nos travaux de these visent a contribuer a cette approche methodologique : ils traitent le developpement d'un emulateur des RCSFs. Pour ce faire deux types de simulateurs ont ete etudies: * le premier est un simulateur " software " base sur la creation de modeles comportementaux, decrits en langage VHDL-AMS. * le deuxieme est un simulateur hardware base sur la creation des modeles logiques comportementaux, decrits en langage VHDL synthetisable. La simulation s'effectuera sur un composant FPGA cible. Des modifications peuvent etre faites sur l'architecture de maniere dynamique.

TL;DR: Mica provides a set of richly interconnected primitives to facilitate cross-layer optimizations and develops customized protocols tailored to their application; Mica does not require use of predefined protocols.
Abstract: Low-power integration of sensing, communication, and computation requires a new approach to wireless design. Flexible interfaces and primitive accelerators enable aggressive system-level optimizations. Mica's flexible design serves as a building block for creating efficient application-specific protocols. Instead of defining narrow, standardized application interfaces, Mica provides a set of richly interconnected primitives (such as data serializers and timing extractors) to facilitate cross-layer optimizations. To explore novel systems approaches, researchers can develop customized protocols tailored to their application; Mica does not require use of predefined protocols.

TL;DR: This work explores the potential for combining GPS collars and satellite images in a WSN to monitor behavioural preferences and social behaviour of cattle and demonstrates the key to combining these technologies is communication methods such as wireless sensor networks.
Abstract: Remote monitoring of animal behaviour in the environment can assist in managing both the animal and its environmental impact. GPS collars which record animal locations with high temporal frequency allow researchers to monitor both animal behaviour and interactions with the environment. These ground-based sensors can be combined with remotely-sensed satellite images to understand animal-landscape interactions. The key to combining these technologies is communication methods such as wireless sensor networks (WSNs). We explore this concept using a case-study from an extensive cattle enterprise in northern Australia and demonstrate the potential for combining GPS collars and satellite images in a WSN to monitor behavioural preferences and social behaviour of cattle.
