Security Issues of Mobile Application Using Cloud Computing

Security issues of the mobile application using cloud computation services are discussed in this paper. Communication between smart phone as a client on the one side and cloud server on the other is described. Security analyse for proposed solution of the health monitoring application is introduced as well. Data about health of the person are one of the most confidential thus need to be secured against different types of threats. Proposed solution is based on the smartphone as a client gathering data and the cloud servers as a computational platform for data storage and analysing. The sensors embedded in the smart phone measure data about monitored person then are partly processed and sent to the server by the internet connection for the deeper analysis.

Cloud based solution for mobile healthcare application

Design of the Watch Dog health care application is presented in this paper. Solution is based on the client running on the smartphone and the server side running in the cloud. Sensors embedded in the smartphone are used for the measurement of the different information about the monitored person such as position, temperature, breath frequency etc. Basic algorithms evaluating current persons health status run on the smartphone. Measured data are sent to the second part of the application running in the cloud for deeper analysis. Suitability of the cloud solution for this application is discussed in this paper.

Communication protocols in substation automation and IEC 61850 based proposal

The automation of control systems of substations in the energy industry uses a variety of specialized standards, technologies and protocols. Among the most frequently used belong MODBUS, IEC60870, DNP3 and IEC61850 protocols. The present paper analyses and compares approaches to data communication among the abovementioned protocols with the main focus on modern standard IEC61850. The paper was created on the basis of experience while implementing data communications for ČEPS a.s., the national distributor in the Czech Republic.

Lower Layers of a Cloud Driven Smart Home System

This presented article introduces utilization of a cloud solution as a part of inovative smart home system (HAUSY - Home Automation System). This solution is based on highly modular structure, which ensures a unique solution for individual implementations. In scope of the presented solution, a universal architecture not requiring a specialized hardware for its utilization is suggested. In the first part, the original three-part smart home system architecture and the functionality of individual layers are introduced. The second part of the article introduces a specific solution for functionalities and communication between individual end nods and microcontrollers. The suggested solution is unique for its option of personalizations of user access and priorities, comfortable interface for defining rules of autonomous operations, and the option of connecting external systems via a unified API with the option of using cloud.

Performance comparison of selected virtualization platforms

The suitability assessment of implemented virtual platform must precede the implementation itself. The aim of the article is to experimentally assess the performance of freely available virtualization tools in several aspects. In the process of virtualization of any environment the performance decreases regarding a host system because of an application of isolating technologies. The performance parameters of CPU, inquired in two different tests, speed of retrieving and writing on a virtualized hard disc and also speed of response of a virtual network interface were chosen for comparison. The aim of the article is also to present the results of testing and chosen tested tools together with used methodology. The measured values are presented in graphs and accompanied by their interpretations. On the grounds of measured values one of the tested virtualization tools is recommended, which measured values shown the best characteristics.

Lightweight Protocol for M2M Communication

Increasing popularity of Internet of Things and Smart home system raises new requirements for micro-controllers. There is a need for affordable solutions with low power consumption and reasonably fast communication transmission rate. This article deals with the communication protocols and introduces own protocol designed for machine to machine communication. Different ways of data transfer between various hardware layers are shown and compared. Every approach is discussed with its benefits and downfalls. Benchmark of three selected types of communication using proposed protocol is performed and results are shown.

Energy efficiency measurements of data center systems

The contribution of virtualising technology is without doubts. Frequently the defence of contribution of virtualization is ungrounded or with very weak argumentative support. UHK (University of Hradec Kralove) carried out a research to verify the validity of these facts. This paper presents a part of the research output. It particularly deals with approaches how to process expected decrease in electric power consumption also in cases of waste heat recuperation. Naturally, these results are partly dependant on regional circumstances (labour and energy prices), but their processing principles are evaluated generally enough to be applicable onto any national environment with functional market economy. The present research is grounded by a case study and is based on a demand to evaluate the contribution of virtualised technology development for a prominent provider of high-capacity personalised print SW solutions.

Security Aspects of Cloud Based Mobile Health Care Application

As mobile computing has become very common, a new vulnerabilities and security threads appeared. Cloud computing is a new distribution model of services for various technologies and solutions including the mobile applications. Mobile cloud computing benefits from the interconnection of these two areas. This approach brings many assets, but on the other hand, also the security risks and potential problems. This paper discuss security aspects of mobile cloud computing with a focus on the developed health care mobile application using cloud computation services. Personal data about health of the person are one of the most confidential thus need to be secured against different types of threats. Proposed solution is based on the smartphone as a client gathering data and the cloud servers as a computational platform for data storage and analysing.

System for Detailed Monitoring of Dog’s Vital Functions

Epilepsy is the most common neurological disorder, affecting 0.6% to 0.75% of dogs. However, it is quite difficult to recognize the start of epileptic seizures. Consequently, the purpose of this article is to explore the devices that may be able to help detect epileptic seizures in dogs, including a discussion of their benefits and limitations.

Design of Universal Hardware Node Board for Smart-Home Automation and the IoT

An affordable way of designing and developing an universal node board that can be used with existing Internet gateways or smart home automation frameworks is presented in this paper. Its design allows connecting almost any available sensor, actuator, or control element. The use of the proposed architecture also decreases the time to deploy a system, as well as the time needed to test and analyze various ideas and scenarios. Future improvements and testing are also discussed.
