Traffic shaping in wireless home networks
Many devices commonly found in wireless home networks such as smartphones, gaming consoles and media servers generate real-time traffic with stringent performance requirements. Since the wireless medium is mostly accessed in a distributed manner (DCF), sensitive traffic needs to be "protected". This work investigates how mechanisms defined in the WiFi standard such as virtual carrier sensing and CTS frames can enable this without requiring any modifications to end devices. ns-3 simulations of this scheme in typical wireless home network configurations show significant performance improvement in the delivery rate of prioritized nodes compared to those using plain DCF.

A cross-layer load-independent link cost metric for wireless mesh networks
We present Cross-layer Unicast Transmission Time (X-UTT), a MAC-aware load-independent link cost metric for 802.11-based wireless mesh networks. X-UTT utilizes information acquired from a network-layer unicast probing system and a MAC-layer monitoring system. It is designed to capture the wireless link capacity and be independent of the load induced by self-interference and cross-interference in a mesh network. We present experiments that validate these two properties on our mesh network testbed. These properties can be further exploited in the design of stable path metrics and routing protocols for wireless mesh networks.
