6LoWPAN Stack Model Configuration for IoT Streaming Data Transmission over CoAP

Abstract: Different protocols have been developed for the Internet of things (IoT), such as the constrained application protocol (CoAP) for the application layer of the IPv6 over low-power wireless personal area networks (6LoWPAN) stack model. Data transmitted over 6LoWPAN are limited by the throughput and the frame size defined by IEEE 805.14.5 standards. Choosing the best configuration for data transmission involves a trade off between the application requirements, the constrained network configuration, the constrained device specifications and IoT application protocols. This paper provides an analysis of message size and structure recommendations for the 6LoWPAN stack model for different network topologies using CoAP. CoAP is a promising application protocol for the 6LoWPAN stack model because it can effectively manage the transmission required functionality in small header UDP packets compared to TCP packets. However, a data model is also required to realize an effective IoT model. While fragmentation and reassembly are supported by CoAP, they should be avoided for this type of model. As for any conceptual model, a high configuration between layers is mandatory. Additionally, the proposed message format is useful for semantic web of things application development and for WSN design and management

Resilient IoT Network for short-range data transmission

The current trends predict an increase of Internet of Things (IoT) devices to the billionths, changing the everyday life of the human race everywhere around the world. However, in order to work reliably these devices will require a means of communication that leverages current technologies allowing them to transmit data at short distances. The ubiquity of Bluetooth Low Energy (BLE) alongside the solid foundations of IPv6 over Low-Power Wireless Personal Area Networks (6LoWPAN) will enable the creation of vast networks of interconnected devices in a reliable and transparent way. Nevertheless the validation of such technologies combination is key before the large deployment of such networks can be started. This work validated such a setup, proving that the reliable communication between devices using 6LoWPAN over BLE can be achieved. The project obtained promising results in terms of transparency between this stack and more traditional Internet Protocol (IP) stacks for multiple distances. The conclusions obtained open the possibility for real world scenario testing and small scale deployment for further validation of 6LoWPAN over BLE.As tendências actuais prevêm um aumento de dispositivos de IoT para a ordem dos milhares de milhão, provocando mudanças no dia a dia de pessoas por todo o mundo. Contudo, para garantir que estes dispositivos funcionam de forma ável, irão necessitar de um meio de comunicação que alavanque as technologias actuais de forma a permitir a comunicação a curtas distâncias. A ubiquidade do BLE combinado com as bases sólidas do 6LoWPAN irão possibilitar a criação de vastas redes de dispositivos ligados entre si de forma con ável e transparente. Contudo a validação desta combinação de tecnologias é essencial antes da implantação em larga escala destes sistemas. Este trabalho validou esta combinação de tecnologias, provando que comunicação entre dispositivos utilizando 6LoWPAN sobre BLE é possível. Este projecto obteve resultados promissores em termos de transparências entre esta e stacks mais tradicionais de protocolos de internet. As conclusões obtidas abrem a possibilidade de testes em cenários reais e de instalação de pequenas redes para maior validação de 6LoWPAN sobre BLE

Low-Power Wireless for the Internet of Things: Standards and Applications: Internet of Things, IEEE 802.15.4, Bluetooth, Physical layer, Medium Access Control,coexistence, mesh networking, cyber-physical systems, WSN, M2M

International audienceThe proliferation of embedded systems, wireless technologies, and Internet protocols have enabled the Internet of Things (IoT) to bridge the gap between the virtual and physical world through enabling the monitoring and actuation of the physical world controlled by data processing systems. Wireless technologies, despite their offered convenience, flexibility, low cost, and mobility pose unique challenges such as fading, interference, energy, and security, which must be carefully addressed when using resource-constrained IoT devices. To this end, the efforts of the research community have led to the standardization of several wireless technologies for various types of application domains depending on factors such as reliability, latency, scalability, and energy efficiency. In this paper, we first overview these standard wireless technologies, and we specifically study the MAC and physical layer technologies proposed to address the requirements and challenges of wireless communications. Furthermore, we explain the use of these standards in various application domains, such as smart homes, smart healthcare, industrial automation, and smart cities, and discuss their suitability in satisfying the requirements of these applications. In addition to proposing guidelines to weigh the pros and cons of each standard for an application at hand, we also examine what new strategies can be exploited to overcome existing challenges and support emerging IoT applications
