Environment-Aware Minimum-Cost Wireless Backhaul Network Planning with Full-Duplex Links
In this work, we address the joint design of the wireless backhauling network
topology as well as the frequency/power allocation on the wireless links, where
nodes are capable of full-duplex (FD) operation. The proposed joint design
enables the coexistence of multiple wireless links at the same channel,
resulting in an enhanced spectral efficiency. Moreover, it enables the usage of
FD capability when/where it is gainful. In this regard, a
mixed-integer-linear-program (MILP) is proposed, aiming at a minimum cost
design for the wireless backhaul network, considering the required rate demand
at each base station. Moreover, a re-tunning algorithm is proposed which reacts
to the slight changes in the network condition, e.g., channel attenuation or
rate demand, by adjusting the transmit power at the wireless links. In this
regard, a successive inner approximation (SIA)- based design is proposed, where
in each step a convex subproblem is solved. Numerical simulations show a
reduction in the overall network cost via the utilization of the proposed
designs, thanks to the coexistence of multiple wireless links on the same
channel due to the FD capability.Comment: Submuitted to IEEE for publicatio
