Wireless mobile backhaul networks have been proposed as a substitute in cases in which wired alternatives are not available due to economical or geographical reasons. In this work, we study the location problem of base stations in a given region where mobile terminals are distributed according to a certain probability density function and the base stations communicate through microwave backhaul...

Introduction: The rapid development of wireless telecommunication technologies over the past decades, has led to significant changes in the exposure of the general public to electromagnetic fields. Nowadays, people are continuously exposed to different sources of electromagnetic fields such as mobile phones, mobile base stations, cordless phones, Wi-Fi routers, and power lines. Therefore, th...

We present Mobipedia, an integrated knowledge base with information about 1 million mobile applications (apps) such as their category, meta-data (author, reviews, rating, release date), permissions and libraries used, and similar apps. The goal of Mobipedia is to integrate unstructured and semi-structured data about mobile apps from publicly available data sources and publish it as Linked Data ...

In the era in which activities performed by mobile users are tracked through various sensing mechanisms, the movement data collected through these sensors is submitted into a data mining algorithm in order to determine the movement pattern. The movement pattern refers to the pattern that mobile users generally take to move from one base location to another base location through multiple interme...

As part of the international efforts for energy conservation and CO2 reduction, migration to an energy-efficient mobile infrastructure is of high importance to the mobile communications industry. For network operators, energy efficiency is much more than a corporate social responsibility topic — it will be one of the key factors for successful operation of large-scale mobile communication servi...

In this paper, we propose how to control the uplink transmit power of a mobile station (MS) during soft handoff in order to reduce the error probability of downlink transmit power control command bit without macro diversity gain at the base station controller (BSC). The uplink transmit power control is based on uplink transmit power control commands from all base stations (BS’s) belonging to th...

An ad hoc network is a collection of wireless mobile hosts forming a temporary network without the aid of any established infrastructure or centralized administration. In such an environment, it may be necessary for one mobile host to want the aid of other hosts in forwarding a packet to its destination, due to the limited range of each mobile host's wireless transmissions. In this paper Ad Hoc...

Most applications for location based services rely on a precise determination of the location of the mobile terminal. Especially in urban and indoor environments multipath propagation leads to very complicated scenarios without line-of-sight between the mobile terminals and the base stations. In these scenarios a localization technique based on simple delay evaluations and/or GPS is not accurat...

In this report, the preliminary results concerning the application of IEEE 802.11 protocol to a transmission between a base station and mobile vehicles are presented. In analysed scenarios, mobile vehicles are in the range of a base station only during the limited period of time, inversely proportional to their velocities. The simulation results of the achieved throughputs are introduced. The p...
