Abstract
Airborne tactical networks (ATNs) is driving the growing development of network-centric warfare by maintaining coverage and providing reach-back to military units. However, the key function of ATNs is impeded by the network ossification that is deep-rooted in the tightly coupled, vertically integrated architecture of traditional ATNs. Network virtualization (NV) can provide a more flexible and scalable ATN architecture as a solution, breaking the tight coupling between applications and network infrastructure. One important aspect of NV is virtual network embedding (VNE), which instantiates multiple virtual networks on a shared substrate network. However, existing efforts are not necessarily optimal for the virtualization of ATNs due to the absence of QoS-compliant capacity for the complex interference in air-combat field. To tackle this difficulty, a reliable interference-aware VNE algorithm, termed VNE-RIA, is proposed to provide reliable guarantee in the coordinated node and link mapping for various airborne tactical virtual networks (ATVNs). In the node mapping, the VNE-RIA adopts a novel node ranking approach to rank all substrate and virtual nodes, considering the complex interference including link interference, environmental noise and malicious attacks. In the link mapping, an improved anypath link mapping approach, based on the anypath routing scheme, is adopted to improve the reliability and efficiency of mapping virtual links by exploiting the unique features of wireless channels and the influence of different transmission rates. Numerical simulation results reveal that VNE-RIA algorithm outperforms typical and latest heuristic wireless VNE algorithms under the complex electromagnetic interference of ATNs.

Summary
The revolution of network-centric warfare has been reshaping the current military communication infrastructure. Considering the negative influence of co-channel interference and noise, some VNE solutions have been proposed in the context of wireless networks [15]–[20], which focus on node mobility [17], [20], co-channel interference [18], fault tolerance [16] and QoS provisioning [15] These wireless embedding algorithms cannot offer high-reliability guarantee for the ATNs with complex electromagnetic interference in the air-combat field. Numerical simulation results reveal that VNE-RIA algorithm performs better than representative and latest heuristic wireless VNE algorithms in terms of longterm average VNR acceptance ratio and average revenue to cost ratio in a continuous time event These compared algorithms only consider the influence of wireless interferences on link mapping and adopt the shortest-path algorithm.
