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 ...

Distributed CSMA with pairwise coding [PDF]

open access: yes2013 Proceedings IEEE INFOCOM, 2013
We consider distributed strategies for joint routing, scheduling, and network coding to maximize throughput in wireless networks. Network coding allows for an increase in network throughput under certain routing conditions. We previously developed a centralized control policy to jointly optimize for routing and scheduling combined with a simple network

Creating a Functional Biomimetic Cartilage Implant Using Hydrogels Based on Methacrylated Chondroitin Sulfate and Hyaluronic Acid

open access: yesGels, 2022
The load-bearing function of articular cartilage tissue contrasts with the poor load-bearing capacity of most soft hydrogels used for its regeneration. The present study explores whether a hydrogel based on the methacrylated natural polymers chondroitin ...

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.

Performance of multichannel CSMA networks [PDF]

open access: yes, 1997
Channel sense multiple access with collision detection (CSMA/CD) is a very simple and efficient way of allowing many stations to transmit messages to a central server down a shared channel.
