Implementing utility-optimal CSMA [PDF]

open access: yes2009 47th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2009
Hundreds of papers over the last two decades have studied the theory of distributed scheduling in wireless networks, including a number of them on stability or utility maximizing random access. Several publications in 2008 studied an adaptive CSMA that in theory can approach utility optimality without any message passing under a number of assumptions ...

Exploiting cognitive wireless nodes for priority‐based data communication in terrestrial sensor networks

open access: yesETRI Journal, 2019
A priority‐based data communication approach, developed by employing cognitive radio capacity for sensor nodes in a wireless terrestrial sensor network (TSN), has been proposed.

CSMA/CQ: A Novel SDN-Based Design to Enable Concurrent Execution of Channel Contention and Data Transmission in IEEE 802.11 Networks

open access: yesIEEE Access, 2017
Conventional 802.11 carrier sense multiple access/collision avoidance (CSMA/CA) networks perform channel contention and data transmission serially over a whole channel. This leads to low throughput efficiency.

Emergency traffic adaptive MAC protocol for wireless body area networks based on prioritization.

open access: yesPLoS ONE, 2019
This paper proposes an emergency Traffic Adaptive MAC (eTA-MAC) protocol for WBANs based on Prioritization. The main advantage of the protocol is to provide traffic ranking through a Traffic Class Prioritization-based slotted-Carrier Sense Multiple ...

Differences in the nocturnal flight activity of insect pests and beneficial predatory insects recorded by light traps: Possible use of a beneficial-friendly trapping strategy for controlling insect pests

open access: yesEuropean Journal of Entomology, 2012
The use of light traps for controlling insect pests is restricted since they kill both pests and beneficial insects. It may be a possible to reduce the numbers of beneficial insects trapped by adjusting nightly trapping time based on differences recorded

CSMA/CCA: A Modified CSMA/CA Protocol Mitigating the Fairness Problem for IEEE 802.11 DCF

open access: yesEURASIP Journal on Wireless Communications and Networking, 2006
Carrier sense multiple access with collision avoidance (CSMA/CA) has been adopted by the IEEE 802.11 standards for wireless local area networks (WLANs). Using a distributed coordination function (DCF), the CSMA/CA protocol reduces collisions and improves

On the stability of flow-aware CSMA [PDF]

open access: yesPerformance Evaluation, 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 is sensed idle.

Harringtonia lauricola Spread in Sassafras Root Systems in the Absence of Its Vector, the Redbay Ambrosia Beetle (Xyleborus glabratus)

open access: yesForest Pathology, Volume 56, Issue 4, August 2026.
ABSTRACT Laurel wilt is a vascular disease caused by a non‐native pathogen (Harringtonia lauricola) and an associated beetle vector (redbay ambrosia beetle; RAB; Xyleborus glabratus) affecting several members of the Lauraceae family in North America, including the ecologically and culturally important sassafras (Sassafras albidum).

A Biomimetic Lubricant Captures Hyaluronic Acid In Situ to Regenerate Cartilage: From Bench to Bedside

open access: yesAdvanced Science, Volume 13, Issue 37, 3 July 2026.
(a) The outstanding lubricative properties of natural articular cartilage arise from a composite coating composed of HA, lubricin, and phospholipids at its surface. Notably, lubricin facilitates the enrichment of synovial HA onto cartilage surfaces, and HA complexes with phospholipids, a key component to maintain extremely low friction under high ...
