Long Term Evolution (LTE) networks are expected to provide enhanced quality of service (QoS) guaranteed services and a high capacity. In this paper, we propose a novel QoS guaranteed cross-layer scheduling algorithm for LTE system. In fact the LTE scheduler is responsible for efficiently allocating the radio resources among mobile users who have different QoS demands. We focus on the resource blocks...
EDCA virtual collision management is a penalizing process that occurs in Intelligent Transportation Systems (ITS). It induces unfairness, priority inversion and quality of service degradation. This paper tackles the performance evaluation of the virtual collision management proposed by IEEE in vehicular environment and overviews the quality of service in presence of three ITS applications: Warning...
The Enhanced Distributed Channel Access (EDCA) mechanism supports some degree of service differentiation between different types of classes of service, referred to as access categories. However virtual collision management is a penalizing process, it can induce quality of service degradation. We propose in this paper a mathematical modelling based on a two-dimension Markov chain and overviews the...
Long Term Evolution (LTE) is the most recent evolution of mobile phone standards; it has been proposed to provide higher throughput and better spectral efficiency. However with the increasing of services applications supported by each device in LTE networks, the resources sharing function is one of the key challenging issues. In this context, Logical Channel Prioritization (LCP) is referred. In this...
