A Testbed Analysis of the Effects of IEEE 802.11s Power Save on Mesh Link Performancey be implemented in software, this allows to bring the benefits of mesh networking to a broad market of about one billion devices. The standard amendment describes new power save schemes which allow efficient energy saving for all mesh nodes. On the downside, the power save schemes will also degrade

Receiver-Initiated vs. Short-Preamble Burst MAC Approaches for Multi-channel Wireless Sensor Networks transmissions. The increase of spectrum utilization in non-licensed bands along with the reduced power used by these nodes is expected to cause high interference problems in WSNs. Therefore, the design of new dynamic spectrum access techniques specifically tailored to these networks plays an impor

White Spaces in UHF Band: Catalonia Case Study and Impact of the Digital Dividendhis paper analyses the TV spectrum occupation in the region of Catalonia, Spain, because it will be one of the first EU regions where changes in the UHF band are going to be implemented. Those changes are derived from the implementation of the Digital Dividend. The goal of this paper is to correlate

A Framework for Security Context Migration in a Firewall Secured Virtual Machine Environment these VMs via Virtual Networks (VNs). These VNs underlie the same security requirements as physical networks. Network elements such as stateful firewalls contribute in enforcing this security. With the advent of stateful firewalls on the hypervisor level, a new challenge arises when it comes to VM
