This document provides a brief introduction and analysis of the simulation tool VanetMobiSim/NS-2 proposed for the simulation of different CARLINK scenarios. 1. For a trustworthy VANETs simulation in CARLINK project it is necessary to use a simulation tool that includes both a traffic simulator and a network simulator. The simulator proposed here is one composed by VanetMobiSim, as a traffic ge...

Channel holding time is of primary importance in teletraffic analysis of PCS networks. This quantity depends on user’s mobility which can be characterized by the cell residence time. In this paper we show that when the cell residence time is not exponentially distributed, the channel holding time is not exponentially distributed either, a fact also confirmed by available field data. In order to...

The acquisition of accurate channel state information at the transmitter (CSIT) is a difficult task in multiple-input multiple-output (MIMO) systems. Partial CSIT is a more realistic assumption, especially for high-mobility mobile users (MUs) whose channel varies very rapidly. In this letter, we propose a MIMO two-way relaying (MTWR) scheme, in which the communication between the BS and a high-...

This paper proposes the Networked Game Mobility Model (NGMM), for synthesising mobility in First-Person-Shooter (FPS) networked games. Current networked game research focuses on modelling low-level aspects, such as packet inter-arrival times and packet sizes, to optimise network traffic and efficient use of gaming servers. Due to the increasing popularity of multiplayer online games, the need h...
