Abstract:

In view of the integration ossification problem, traditional airborne networks have difficulty in allocating network resources to recover quickly from node failure and complete corresponding missions. Therefore, a node reliability-aware protection-differentiated virtual airborne network embedding (NRPD-VANE) algorithm is proposed for airborne networks in the wireless network virtualization environment. Firstly, node mapping adopts a novel node ranking method that comprehensively considers node failure possibility, wireless interference and network resources in order to map virtual nodes onto reliable substrate nodes. Secondly, link mapping adopts the efficient P-Cycle protection technology to protect the unreliable substrate nodes on the path that maps corresponding virtual links. Simulation results show that comparing with other latest node protection embedding algorithms, the proposed algorithm improves the embedding success ratio while maintaining a low average recovery delay.

Key words: airborne network, network virtualization, virtual network embedding, protection-differentiated, node failure, P-Cycle
