Performance analysis of uplink scheduling algorithms in the urban and rural environments in LTE / Shafinaz Ismail, Darmawaty Mohd Ali and Norsuzlia Ya'acob

Long Term Evolution (LTE) is the evolution of an
existing 3G mobile network towards a higher capacity, a lower
latency and a more efficient core network and radio access. LTE
was chosen in order to deliver higher data rate and application
demands with trustworthy and reliable connections. This paper
makes an attempt to study and compare the performance of two
well-known uplink schedulers namely, First Maximum
Expansion (FME), and Round Robin (RR). The evaluation is
considered for a single cell with three flows, which are the Best
Effort, video, and VoIP in an urban and rural environment using
the LTE-SIM network simulator. The comparative study is
conducted in terms of system throughput, fairness index, delay
and packet loss ratio (PLR). The simulation results show that RR
algorithm always reaches the lowest PLR among those strategies
and RR is the most suitable scheduling algorithms for VoIP and
video flows while FME is better for BE flows in both urban and
rural environment in LTE networks.
