Robust and Listening-Efficient Contention Resolution
, 2023 This paper shows how to achieve contention resolution on a shared communication channel using only a small number of channel accesses -- both for listening and sending -- and the resulting algorithm is resistant to adversarial noise. The shared channel

Performance analysis of general backoff protocols
Journal of Communications Software and Systems, 2008 In this paper, we analyze backoff protocols, such as the one used in Ethernet. We examine a general backoff function(GBF) rather than just the binary exponential backoff (BEB) used by Ethernet. Under some mild assumptions we find stability and optimality

Resolving 5G NR-U Contention for Gap-Based Channel Access in Shared Sub-7 GHz Bands
IEEE Access, 2022 New Radio Unlicensed (NR-U) enables 5G networks to operate in unlicensed channels, including the sub-7 GHz bands where transmitters are required to adhere to a set of contention resolution rules known as listen before talk (LBT).

Implicit Transformer Network for Screen Content Image Continuous Super-Resolution [PDF]
arXiv, 2021 Nowadays, there is an explosive growth of screen contents due to the wide application of screen sharing, remote cooperation, and online education. To match the limited terminal bandwidth, high-resolution (HR) screen contents may be downsampled and compressed.

Scene Text Image Super-Resolution via Content Perceptual Loss and Criss-Cross Transformer Blocks [PDF]
arXiv, 2022 Text image super-resolution is a unique and important task to enhance readability of text images to humans. It is widely used as pre-processing in scene text recognition. However, due to the complex degradation in natural scenes, recovering high-resolution texts from the low-resolution inputs is ambiguous and challenging.

Enhancing the Selection of Backoff Interval Using Fuzzy Logic over Wireless Ad Hoc Networks
The Scientific World Journal, 2015 IEEE 802.11 is the de facto standard for medium access over wireless ad hoc network. The collision avoidance mechanism (i.e., random binary exponential backoff—BEB) of IEEE 802.11 DCF (distributed coordination function) is inefficient and unfair ...

The Outer Limits of Contention Resolution on Matroids and Connections to the Secretary Problem [PDF]
arXiv, 2019 Contention resolution schemes have proven to be a useful and unifying abstraction for a variety of constrained optimization problems, in both offline and online arrival models. Much of prior work restricts attention to product distributions for the input set of elements, and studies contention resolution for increasingly general packing constraints ...

Contention Resolution Without Collision Detection [PDF]
arXiv, 2020 This paper focuses on the contention resolution problem on a shared communication channel that does not support collision detection. A shared communication channel is a multiple access channel, which consists of a sequence of synchronized time slots. Players on the channel may attempt to broadcast a packet (message) in any time slot.

Coded Slotted ALOHA with Varying Packet Loss Rate across Users
, 2013 The recent research has established an analogy between successive interference cancellation in slotted ALOHA framework and iterative belief-propagation erasure-decoding, which has opened the possibility to enhance random access protocols by utilizing ...
