Abstract

The Internet of things has profoundly changed the way we imagine information science and architecture, and smart homes are an important part of this domain. Created a decade ago, the few existing prototypes use technologies of the day, forcing designers to create centralized and costly architectures that raise some issues concerning reliability, scalability, and ease of access which cannot be tolerated in the context of assistance. In this paper, we briefly introduce a new kind of architecture where the focus is placed on distribution. More specifically, we respond to the first issue we encountered by proposing a lightweight and portable messaging protocol. After running several tests, we observed a maximized bandwidth, whereby no packets were lost and good encryption was obtained. These results tend to prove that our innovation may be employed in a real context of distribution with small entities.

Highlights

  • The evolution of our society towards the all-digital Internet of things (IoT) has profoundly remodeled our relationship with the science of information

  • The vast majority of work with respect to the domain of smart homes focuses on an activity recognition problem in order to potentially assist inhabitants with dementia often caused by advanced age [4,5,6]

  • According to the Gator Tech and Center for Advanced Studies in Adaptive Systems (CASAS) cases, it seems that embedding some intelligence and communication abilities in them helps to reduce costs and ease installation and scalability

Summary

Introduction

The evolution of our society towards the all-digital Internet of things (IoT) has profoundly remodeled our relationship with the science of information. We briefly introduce a new kind of smart home architecture providing both reliability and scalability based on low-cost smart sensors. To achieve this objective, the first issue we ran into was the difference between all the possible entities in the environment. Sensors 2016, 17, 2397 hardware (e.g., computers or micro-controllers) and using different communication technologies (e.g., Wi-Fi, ZigBee or 6LowPan) To respond to these dissimilarities, we have to use a highly portable communication protocol using brokerless architecture to provide the greatest reliability. This point will be the main concern of this paper. Conclusions and some future works are found at the end of this paper
