—In this paper, we present a channel sensitive transmission scheme which reduces the negative impact of Vehicle-to-Infrastructure (V2I) traffic on the Quality of Services (QoS) of Human to Human (H2H) communication in cellular networks.
In this poster the results of an accurate, measurement-based power consumption profiling of Long Term Evolution (LTE) User Equipment (UE) are presented together with concrete model parameter sets for four different most recent LTE data sticks and one LTE smart phone. In contrast to existing power consumption models for cellular devices, the model presented… (More)
—The number of Machine-to-Machine (M2M) applications is rapidly increasing in cellular communication systems. In order to ensure a maximum system capacity, the impact of this special kind of traffic on common Human-to-Human (H2H) communication needs to be analyzed. In this paper, a system model for performance evaluation of cellular networks like Long Term… (More)
The performance evaluation of mobile communication systems for time varying environments poses a major challenge. To address this issue, in this paper we propose an approach which extends a common laboratory environment by a fading channel emulator. Hereby, we analyze OFDM based links under complex and realistic radio channel conditions including upper… (More)
The energy that has to be spent for the successful submission of one Bit is an important figure of merit for the performance analysis and optimization of modern wireless communication systems. The many factors which are influencing this performance parameter range from the efficiency of the User Equipment's (UE) power amplifier to the average path loss, the… (More)
—In this paper, an energy efficient approach for the transmission of Floating Car Data (FCD) via Long Term Evolution (LTE) is presented. Applying channel sensitive transmission, FCD is collected by mobile devices in cars and transmitted preferably if the channel conditions are good. The results show that this approach reduces the negative impact on the… (More)
The IEEE 802.16e mobile WiMAX standard allows for a wide variety of different application. Especially in cases where people rely on high speed network access in greater areas which is exclusively dedicated to them mobile WiMAX is a viable solution. One of these scenarios is the control of a swarm of miniature unmanned aerial vehicles (MUAV). These flying… (More)
For the reliable control of Micro Unmanned Aerial Vehicles (MUAV) using IP based networks it is of high importance to assure certain quality of service warranties for the transmission of control information. The mobile WiMAX standard IEEE 802.16e defines five QoS Classes which represent different requirements concerning data rate and delay. The scheduling… (More)
