High-Throughput Random Access via Codes on Graphs [PDF]

open access: yes, 2010
Recently, contention resolution diversity slotted ALOHA (CRDSA) has been introduced as a simple but effective improvement to slotted ALOHA. It relies on MAC burst repetitions and on interference cancellation to increase the normalized throughput of a ...

Millimeter Wave Ad Hoc Networks: Noise-limited or Interference-limited?

open access: yes, 2015
In millimeter wave (mmWave) communication systems, narrow beam operations overcome severe channel attenuations, reduce multiuser interference, and thus introduce the new concept of noise-limited mmWave wireless networks.

Sloppy-slotted ALOHA [PDF]

open access: yes
Random access signaling, which allows slotted packets to spill over into adjacent slots, is investigated. It is shown that sloppy-slotted ALOHA can always provide higher throughput than conventional slotted ALOHA. The degree of improvement depends on the

High-SIR Transmission Capacity of Wireless Networks with General Fading and Node Distribution

open access: yes, 2010
In many wireless systems, interference is the main performance-limiting factor, and is primarily dictated by the locations of concurrent transmitters. In many earlier works, the locations of the transmitters is often modeled as a Poisson point process ...

Stability Analysis of Hybrid ALOHA

open access: yesEURASIP Journal on Wireless Communications and Networking, 2010
We perform stability analysis of a recently proposed MAC protocol, hybrid ALOHA, based on the multipacket reception (MPR) model. Hybrid ALOHA distinguishes from conventional slotted ALOHA by allowing conditional collision-free channel estimation and ...
