(English Abstract) |
In this paper, we consider the problem of joint congestion and power control over time-varying channels for all
secondary user (SU) nodes communicate each other in multi-hop cognitive radio network (CRN). Firstly, we consider
how SUs transmit data from infinite transmission buffer to maximize its utility under constraints on tranmission cost
without affecting primary user (PU) activity. Then we propose a distributed algorithm for jointly optimal rate and
power control (JORPC) via message passing to achieve a joint performance. Finally, the simulation results demonstrate
that the proposed algorithm achieves significantly high utility and energy efficiency when comparing to existing
works which the optimization-based cross layer design between physical and transport layer has not been thoughtfully
taken into consideration in CRNs yet. |
