Survivability-Enhanced Virtual Network Embedding Strategy in Virtualized Wireless Sensor Networks. [PDF]
Sensors (Basel), 2020 With the widespread application of wireless sensor networks (WSNs), WSN virtualization technology has received extensive attention. A key challenge in WSN virtualization is the survivable virtual network embedding (SVNE) problem which efficiently maps a virtual network on a WSN accounting for possible substrate failures.

Virtual Network Embedding Based on Graph Entropy [PDF]
Entropy, 2018 For embedding virtual networks into a large scale substrate network, a massive amount of time is needed to search the resource space even if the scale of the virtual network is small.

Network virtualization and programmability [PDF]
, 2010 We present network virtualization (building virtual or logical networks over a physical infrastructure) and network programmability (allowing the network operator to at least control the network but more fundamentally to define its behavior ...

Wireless network virtualization [PDF]
2013 International Conference on Computing, Networking and Communications (ICNC), 2013 Virtualization of wired networks and end computing systems has become one of the leading trends in networked ICT systems. In contrast relatively little virtualization has occurred in infrastructure based wireless networks, but the idea of virtualizing wireless access is gaining attention as it has the potential to improve spectrum utilization and ...
