Abstract
With the densification of nodes in cellular networks,

free space optic (FSO) connections are becoming an appealing

low cost and high rate alternative to copper and fiber backhaul

solutions for wireless communication systems. To ensure a reliable

cellular backhaul, provisions for redundant disjoint paths

between the nodes must be made in the design phase. This paper

aims at finding a cost-effective solution to upgrade the cellular

backhaul with pre-deployed optical fibers using FSO links and

mirror components. Since the quality of the FSO links depends

on several factors, such as transmission distance, power, and

weather conditions, we adopt an... (More)
With the densification of nodes in cellular networks,

free space optic (FSO) connections are becoming an appealing

low cost and high rate alternative to copper and fiber backhaul

solutions for wireless communication systems. To ensure a reliable

cellular backhaul, provisions for redundant disjoint paths

between the nodes must be made in the design phase. This paper

aims at finding a cost-effective solution to upgrade the cellular

backhaul with pre-deployed optical fibers using FSO links and

mirror components. Since the quality of the FSO links depends

on several factors, such as transmission distance, power, and

weather conditions, we adopt an elaborate formulation to calculate

link reliability. We present a novel integer linear programming

model to approach optimal FSO backhaul design, guaranteeing

K-disjoint paths connecting each node pair. Next, we derive

a column generation method to a path-oriented mathematical

formulation. Applying the method in a sequential manner enables

high computational scalability. We use realistic scenarios to

demonstrate that our approaches efficiently provide optimal or

near-optimal solutions, and thereby allow for accurately dealing

with the trade-off between cost and reliability. (Less)
