Abstract— The IEEE 802.11e standard has recently been ratified. This standard provides Quality-of-Service (QoS) guarantees in the Medium Access Control (MAC) layer of 802.11 Wir...
It has been shown that IEEE 802.11 DCF medium access control (MAC) protocol may not be suitable for multihop wireless networks due to its relatively low throughput and severely un...
Carrier sense is often used to regulate concurrency in wireless medium access control (MAC) protocols, balancing interference protection and spatial reuse. Carrier sense is known ...
The many-to-one multihop traffic pattern of Wireless Sensor Networks (WSN) puts a great challenge on enhancing the event-to-sink data delivery throughput. Because, in CSMA/CA dri...
—We address the problem of collaborative sensing in cognitive radios. In a cognitive radio network, all the nodes may sense the spectrum simultaneously. They should then exchange...

The requirements of multimedia underwater monitoring applications with heterogeneous traffic demands in terms of bandwidth and end-to-end reliability are considered in this artic...
Due to hidden terminals and a dynamic topology, contention among stations in an ad-hoc network is not homogeneous. Some stations are at a disadvantage in opportunity of access to ...
