Wireless protocol design for smart home on mesh wireless sensor network

This paper proposes a formulation scheme for communication data protocol at the application layer that can adapt to heterogeneous smart objects which may arise in the case of Smart Home application. Mesh-based design WSN is an attempt to realize the Smart Home concept, where DigiMesh topology is chosen as the basic topology in experimental setup of WSN. Mobile device is the main object as monitoring and controlling devices. Mapping the address and description of each bit in a predetermined protocol, then can be implemented in various condition. With the dynamic characteristics of the design of this protocol, the power cost can be reduced to a minimum. Protocol design has been successfully tested in scenario of monitoring and controlling function. Application of the CheckSum method is also reported to help in the detection error of data packet.

Rapid Prototyping Methodology of Lightweight Electronic Drivers for Smart Home Appliances

Many researches have been conducted in smart home topic. Mostly, they discussed on the specific aspect of application. On the other side, many applications still can be explored and attached into the system. Several main challenges in designing the application devices are system complexity, reliability, user friendliness, portability, and low power consumption. Thus, design of electronic driver is one of the key elements for overcoming these challenges. Moreover, the drivers have to comply the rules of smart home system, data protocol, and application purpose. Hence, we propose a rapid prototyping methodology on designing lightweight electronic drivers for smart home appliances. This methodology consists of three main aspects, namely smart home system understanding, circuitry concept, and programming concept. By using this method, functional and lightweight drivers can be achieved quickly without major changes and modifications in home electrical system. They can be remotely controlled and monitored anytime and from anywhere. For prototyping, we design several drivers to represent common electronic and mechanical based applications. Experimental results prove that the proposed design methodology can achieve the research target. Full Text: PDF DOI: http://dx.doi.org/10.11591/ijece.v6i5.11279

Design of low power mobile application for Smart Home

Design and implementation of smart home app is one of Internet-of-Things (IoT) topic which need to be explored more. Its major challenges are about capability on automatic adjustment with various operating system (OS), simple, efficient, compact and interactive. One of the most important issue is the battery consumption. Hence, this research aims is to develop an Android based low-power mobile application for smart home. This application design covers multi-control scheme (i.e. hard-control, soft-control and monitoring). Meanwhile, in order to investigate the battery consumption, we analyze few aspects, namely the effect of idle-active condition and difference color theme (i.e. red, green and blue).

Smart home platform based on optimized wireless sensor network protocol and scalable architecture

In this paper, we propose a smart home platform based on optimized wireless sensor network (WSN) protocol and scalable architecture. In this platform, system environment is divided into two main environments, indoor and outdoor. Outdoor environment uses internet-cloud system, while indoor environment uses WSN system. This scheme is also well known as Internet-of-Things (IoT) concept. Those two environments are connected to each other by using access point bridge. WSN system is established from efficient and scalable WSN components. Each component of WSN is designed to use an optimized protocol. WSN components are connected to each other in mesh topology in order to provide scalable architecture for further extension and changes. For outdoor environment, the existing internet-cloud system is used as infrastructure. Thus, this smart home platform can be monitored and controlled from smart phone, anytime and anywhere, as long as mobile data access is provided. For databasing implementation, SQLite database system is chosen because of its low cost and easy configuration. For system evaluation, several tests have been conducted to deliver the profile of proposed system.

Modelling and simulation of parallel triangular triple quantum dots (TTQD) by using SIMON 2.0

This research presents analysis of modeling on Parallel Triple Quantum Dots (TQD) by using SIMON (SIMulation Of Nano-structures). Single Electron Transistor (SET) is used as the basic concept of modeling. We design the structure of Parallel TQD by metal material with triangular geometry model, it is called by Triangular Triple Quantum Dots (TTQD). We simulate it with several scenarios using different parameters; such as different value of capacitance, various gate voltage, and different thermal condition.

Live demonstration: MINDS — Meshed and internet networked devices system for smart home: Track selection: Embedded systems

Meshed and Internet Networked Devices System (MINDS) is an Internet-of-Things (IoT) based platform designated for smart home applications. MINDS uses meshed wireless sensor network (WSN) concept to connect and coordinate all of the end-devices (drivers) for home appliances. Theoretically, MINDS can be controlled and monitored by user via smart-phone, anytime and from anywhere. The state-of-the-art of MINDS is started from the efficient data protocol design. It is followed by circuit design for specific drivers, hardware mounting, software programming, testing, and packaging. Target of this research is to propose an efficient and a lightweight system platform for smart home, without major changes on home electrical system. For prototyping purpose, we design several representative functions which cover electronic and mechanical drivers. All of them have been proven to work properly as expected.
