POWER ALLOCATION FOR STATISTICAL QOS PROVISIONING IN

OPPORTUNISTIC MULTI-RELAY DF COGNITIVE NETWORKS

ABSTRACT:

We propose a power allocation scheme for statistical quality-of-service (QoS) provisioning in

multi-relay decode-and-forward (DF) cognitive networks (CN). By considering the direct link

between the source and destination, the CN first chooses the transmission mode (direct

transmission or relay transmission) based on the channel state information. Then, according to

the determined transmission mode, efficient power allocation will be performed under the given

QoS requirement, the average transmit and interference power constraints as well as the peak

interference constraint.

Our proposed power allocation scheme indicates that, in order to achieve the maximum

throughput, at most two relays can be involved for the transmission. Simulation results show that

our proposed scheme outperforms the max-min criterion and equal power allocation policy.
