Multi-Round Contention in Wireless LANs with Multipacket Reception [PDF]
, 2010 Multi-packet reception (MPR) has been recognized as a powerful capacity-enhancement technique for random-access wireless local area networks (WLANs). As is common with all random access protocols, the wireless channel is often under-utilized in MPR WLANs.

Spectrum scanning and reserve channel methods for link maintenance in cognitive radio systems [PDF]
, 2008 Underutilization of the limited spectrum sparked the need for dynamic spectrum access and flexible spectrum policies. Accurate estimation of spectrum occupancy is an essential step for spectrum access in distributed networks.

On the stability of flow-aware CSMA [PDF]
, 2010 We consider a wireless network where each flow (instead of each link) runs its own CSMA (Carrier Sense Multiple Access) algorithm. Specifically, each flow attempts to access the radio channel after some random time and transmits a packet if the channel ...

Physical Channel Access (PCA): Time and Frequency Access Methods Simulation in NS-2 [PDF]
, 2013 We present an NS-2 module, Physical Channel Access (PCA), to simulate different access methods on a link shared with Multi-Frequency Time Division Multiple Access (MF-TDMA). This technique is widely used in various network technologies, such as satellite
