Abstract:
Long Term Evolution(LTE)can support
multimedia services.To guarantee the different
requirements of the different services, packet scheduler
plays an important role in LTE. Especially, the
additional challenges are exposed to the design of
scheduler when real time traffics such as VoIP (voice
over IP) are transmitted over the LTE network.In this
paper, a new scheduler is proposed for satisfying the
different QoS requirements. This scheme distinguishes
whether this connection is real time or not and give the
high priority to real time traffics which are closing to
time out. After scheduling allreal time traffics, delay
tolerant traffics are scheduled.The performance of the
proposed scheduling schemeis evaluated in terms of
throughput, average delay and fairness. The result will
be proofed by comparing with another LTE downlink
schedulers.
