TL;DR: This paper deals with the proposal of efficient adaptive modulation and coding techniques to be used in WiMAX based wireless networks, that allow to improve network performance in the case of Non Line-of-Sight communications, which are typical in urban environments.

TL;DR: This paper model task offloading in MEC as a constrained multi-objective optimization problem (CMOP) that minimizes both the energy consumption and task processing delay of the mobile devices and designs an evolutionary algorithm that can efficiently find a representative sample of the best trade-offs between energy Consumption and task Processing delay.

TL;DR: Focusing on the latter, the impact of large delays and Doppler shifts on LTE PHY/MAC procedures is discussed and assessed and it will be shown that, while carrier spacings, Random Access, and RN attach procedures do not pose specific issues, HARQ requires substantial modifications.

TL;DR: In this paper, the authors present the initial results of the recently kicked-off FP7 ICT STREP project "CoRaSat" (Cognitive Radio for Satellite Communications) focusing on the preliminary identification of the scenarios which are suitable for the applicability of Cognitive Radio technology over Satellite Communications (SatCom).

TL;DR: Two different adaptive subcarrier allocation algorithms are proposed and analyzed and their aim is to share the network bandwidth among users on the basis of specific channel conditions without loosing bandwidth efficiency and fairness.
