The paper presents proposal of practical implementation simple IoT gateway based on Arduino microcontroller, dedicated to use in home IoT environment. Authors are concentrated on research of performance and security aspects of created system. By performed load tests and denial of service attack were investigated performance and capacity limits of implemented gateway.
This paper presents concept and prototype of universal easy-to-use and self-configurable mobile application dedicated for open data sets collection and sending them to the central database storage based on CKAN platform. This article describes the concept of open data collection in crowdsourcing model using mobile phones and also an architecture of end user application (CKAN client) dedicated for...
The paper presents an anonymization of telecommunication data sets collected through Service Delivery Platforms (SDP), and describes an example tool SDPAnonymizer to make such operation. Information from SDP are processed in form of log files, consisting data sets, which show activity of users of APIs (Application Programming Interfaces). Data sets which should be anonymized contain sensitive data,...
This paper presents an idea of new communication Application Programming Interfaces (APIs) based on graph oriented data stored in database. The use case described in paper allows the sending of traditional telecommunication messages (SMS or USSD) to dedicated people identified as best recipients based on their skills and location. A decision algorithm implemented in API, besides the organizational...
The main objective of this paper is proposition simple, easy to implementation and low cost solution dedicated for parking lots reservation. The presented application uses Unstructured Supplementary Service Data (USSD) as an communication channel between driver and parking system. USSD communication proposed in this paper is more efficient and comfortable for the end user in comparison with SMS used...
The paper presents an idea of a context-aware application, which collects context data from many different sources, stores them in a dedicated database and makes use of it to support flexible scenarios for end users. Using open APIs it integrates different types of context information provided by: Unified Communication system, APIs exposed by communication service providers and information from Machine...
We propose conception of the identification and forecasting of threatening situations in a Smart Space. This applies to the problem of public safety hazards caused by natural disasters, human activity, equipments failures, and is the important element of a proper functioning of modern society. Protection against threats is becoming increasingly possible with the development of "Smart Connected...
This paper presents possibility to use Telco 2.0 architecture interfaces to realize a service supporting public transport in agglomerations. Such systems are expected to be easily accessible for everyone and to be available in any location. Such expectations may only be met by a system using the latest achievements in the scope of telecommunication, which are API based on telecommunication operator's...
The paper presents the idea of Telco 2.0 with an e-health usage scenario. Since numerous elderly people are going missing every year, proposed emergency location service depicts a way in which mobile operators' networks, the Internet and possibilities given by rapid improvement of smart-phones' functionalities can converge in order to relieve the problem. The descriptions are supplemented with sets...
This paper presents practical integration of enterprise Unified Communications system with telecommunication service provider Service Delivery Platform. System implemented in Orange Labs, enables sending SMS and USSD messages geo-localizing of user mobile terminal directly from user interface of Unified Communications system. This article presents also statement regarding further investigations in...
The rejection of heat generated by components and circuits is a very important aspect in design of electronics systems. Heat pipes are very effective, low cost elements, which can be used in cooling systems. This paper presents the modelling and measurements of the heat and mass transfer in heat pipes. The physical model includes the effects of liquid evaporation and condensation inside the heat pipe...
