This paper proposes a new approach based on optimal transport theory to model network topologies for purpose of strategic planning and optimal design. We study the SINR mobile association game: we determine the cells corresponding to each base station, i.e., the locations at which mobile terminals prefer to connect to a given base station rather than to others. The Signal to Interference plus N...

Radio channel characteristics of mobile nodes are quite different compared with the traditional stationary base station to mobile radio channel. Wireless link reliability estimation is necessary for self-organization of wireless mobile multihop networks. In this paper, we measure narrowband path loss measurements in a typical mobile-to-mobile radio environment. For application, we proposed a me...

Customary network migration to Next Generation Networks (NGN) is due to service integration and low cost of the offered services in NGN. NGN is based on an IP/MPLS backbone through which all traffics pass. Besides, different mobile generations up to R99 UMTS are all based on the circuit switch systems. Thus the connections to NGN may cause some challenges. In this paper, to provide these connec...

This paper examines the use of mobile telephony in public spaces. It looks into the issue of how and why mobile telephony is seen as being disturbing. The two major issues are first, the way in which the device disturbs the web of front and back channel interactions found in a social setting and second the difficulties of managing issues surrounding eavesdropping and courtesy. The paper bases i...

Abstract: Network capacity region is an important character for a mobile ad hoc network. This paper, using cell-partitioned model, an analytical expression of the upper bound of a delay-tolerant hybrid mobile ad hoc network is deduced, regardless of coverage of base stations, the type of mobile process and the scheduling and routing algorithms. The limitation of the upper bound has been derived...

QoS is essential, but for mobile environment, it is difficult to achieve QOS when compared to wired network due to poor communication environment and mobility problems. In this document we explore the prominent efforts done in literature to provide schemes to do QoS in Wireless. We especially concentrate on resource reservation schemes. This document addresses cellular network QoS (mobile user ...

The deployment of a miniature mobile-phone base station or small cell in a train car significantly improves the coverage and the capacity of a mobile network service on the train. However, the impact of the small cell on the passengers' exposure to radio-frequency electromagnetic fields (RF-EMF) is unknown. In this study, we assessed experimentally the RF-EMF exposure of a mobile-phone user who...

Smartphones have become essential devices for the daily activities that the human being performs. Its proliferation has increased the cellular infrastructure in an effort of the mobile operators to satisfy the demand. Due to the cellular network planning is performed considering the peak hour, a large number of base stations are deployed, maintaining the same number of base stations even in low...

In traditional cellular systems with xed base stations the channel reuse pattern is static and deterministic. When the cell layout is dynamic, due to the mobility of base stations, the cluster of cells within co-channel interference range changes with time. Consequently, the channel reuse pattern is highly dynamic. Moreover, base stations also need wireless channels to communicate amongst thems...

mobile carrier properties of two schiff base ligands, named bis(2-hydroxypropiophenone)-1,2-propanediimine (n2o2) and bis(1'-hydroxy-2'-acetonaphthone)-2,2'-diiminodiethylamine (n3o2), dissolved in dichloromethane for the extraction of copper(ii) ions from an ammonium buffer feed phase into a nitric acid solution (receiving phase) were investigated and compared. the parameters influencing the t...
