A substantial percentage of links in wireless networks, especially low-power ones, is asymmetric. For the low-quality direction of asymmetric links, we observe based on testbed ex...
Relay-assisted cooperative wireless communication has been shown to have significant performance gains over the legacy direct transmission scheme. Compared with single relay base...

The IEEE 802.11x MAC protocol, the de facto standard for wireless LANs, includes a distributed coordination function (DCF) mode usable for ad hoc network architectures. The Transm...
Network congestion occurs when offered traffic load exceeds available capacity at any point in a network. In wireless sensor networks, congestion causes overall channel quality t...
