Résumé:
In order to enhance the Quality of Service in LTE,
femtocell architecture has been proposed as a promising solution.
However, interference is the main weak point in femtocell
scenarios which causes a serious impact on multimedia services
performance. Femtocell interference mitigation in LTE networks
is the principle objective of this paper. We propose an enhancement
of the well known four-coloring method for interference
mitigation by combining it with cooperative game theory. Our
proposed scheme aims to provide a solution to effectively achieve
femtocell interference mitigation while guaranteeing the bitrate
application for real-time services. The basic metrics of quality
of service (QoS) such as throughput, Packet Loss Ratio (PLR),
delay and Signal-to-Interference-plus-Noise-Ratio (SINR) are
investigated. Our simulation environment is derived from realistic
scenarios in order to study the performance of real-time service
like Video and VoIP applications. Throughout our numerical
results, we demonstrate the improvement of QoS constraints
along with balancing between interference reduction requirement
and resource allocation efficiency for real-time applications.
