Cloudsim power allocation for statistical qo s provisioning in opportunistic multi-relay df cognitive networks
0 likes162 views
The document proposes a power allocation scheme for statistical quality-of-service provisioning in multi-relay cognitive networks. The scheme first chooses between direct transmission or relay transmission based on channel state information. It then performs efficient power allocation according to the transmission mode and given constraints like quality-of-service requirements, average transmit power limits, and peak interference limits. Simulations show the proposed scheme outperforms max-min criterion and equal power allocation policies by achieving higher throughput while involving at most two relays for transmission.

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.
