Geo-location for Telecom Operators

Our new paper: Dmitry Namiot, Manfred Sneps-Sneppe "On Geo Location Services for Telecom Operators"

This paper presents location based service for telecom providers. Most of the location-based services in the mobile networks are introduced and deployed by Internet companies. It leaves for telecom just the role of the data channel. Telecom providers should use their competitive advantages and offer own solutions. In this paper, we discuss the sharing location information via geo-messages. Geo messages let mobile users share location information as signatures to the standard messages (e.g., email, SMS). Rather than let some service constantly monitor (poll) the user location (as the most standalone services do) or share location info within any social circle (social network check-in, etc.) The Geo Messages approach lets users share location data on the peer to peer basis. Users can share own location info with any existing messaging systems. And messaging (e.g., SMS) is the traditional service for telecom.

On Mobile Mesh Networks

With the advances in mobile computing technologies and the growth of the Net, mobile mesh networks are going through a set of important evolutionary steps. In this paper, we survey architectural aspects of mobile mesh networks and their use cases and deployment models. Also, we survey challenging areas of mobile mesh networks and describe our vision of promising mobile services. This paper presents a basic introductory material for Masters of Open Information Technologies Lab, interested in modern mobile services.

Metadata in SDN API

Our paper in arxiv: Dmitry Namiot, Manfred Sneps-Sneppe "Metadata in SDN API"

This paper discusses the system aspects of development of applied programming interfaces in Software-Defined Networking (SDN). Almost all existing SDN interfaces use so-called Representational State Transfer (REST) services as a basic model. This model is simple and straightforward for developers, but often does not support the information (metadata) necessary for programming automation. In this article, we cover the issues of representation of metadata in the SDN API.

On Indoor Positioning

A new paper: Namiot, Dmitry. "On Indoor Positioning." International Journal of Open Information Technologies 3.3 (2015): 23-26.

This paper presents the survey of the modern indoor positioning technologies and systems. We discuss Wi-Fi and Bluetooth based positioning systems, light-based and magnetic field systems. It is our first attempt to classify indoor positioning techniques. We try to highlight the advantages and disadvantages of various indoor positioning technologies and systems, compare their accuracy, applicability, working principles and performance parameters.
