Analysis of fibre-loop optical buffers with a void-avoiding schedule [PDF]
EAI Endorsed Transactions on Internet of Things, 2015 In optical packet/burst switching, fibre-loop optical buffers provide a compact and effective means of contention resolution. In case of fixed packet length, the involved loop length is typically chosen matched (equal to the packet length), and the loops

Energy-Constrained Design of Joint NOMA-Diversity Schemes with Imperfect Interference Cancellation
Sensors, 2021 This study proposes a set of novel random access protocols combining Packet Repetition (PR) schemes, such as Contention Resolution Diversity Slotted Aloha (CRDSA) and Irregular Repetition SA (IRSA), with Non Orthogonal Multiple Access (NOMA). Differently

A NOVEL HYBRID SCHEME FOR CONTENTION MINIMIZATION IN OPTICAL BURST SWITCHED NETWORK [PDF]
ICTACT Journal on Communication Technology, 2015 In Optical Burst Switched (OBS) Networks, data is transported in a bufferless network and hence there is fair amount of possibility of contention among the data bursts. This occurs when multiple bursts contend for the same link.

Journal of the European Optical Society-Rapid Publications, 2020 Signal buffering services such as contention resolution and congestion avoidance are essential in optical packet switching networks. In this paper, an optical memory scheme based on spectral amplitude coding (SAC) and complementary code keying (CCK) is ...

QoS provisioning for Composite Burst Assembly with Burst Segmentation in Optical Burst Switching (OBS) Networks [PDF]
Kirkuk Journal of Science, 2015 Optical Burst Switching (OBS) is one of the suggested that switching paradigms be used in Internet-Protocol over Wavelength Division Multiplexing (IP over WDM) networks along with Optical Circuit Switching (OCS) and Optical Packet Switching (OPS).

CONTENTION RESOLUTION IN OPTICAL BURST SWITCHES USING FIBER DELAY LINE BUFFERS [PDF]
Journal of Engineering Science and Technology, 2017 Optical burst switching (OBS) is a circuit switching paradigm that provides very high throughput with reasonable delay. In OBS, the data burst size is not uniform and can be of any length.

Strategic Contention Resolution with Limited Feedback [PDF]
CoRR, 2016 In this paper, we study contention resolution protocols from a game-theoretic perspective. We focus on \emph{acknowledgment-based} protocols, where a user gets feedback from the channel only when she attempts transmission. In this case she will learn whether her transmission was successful or not.

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

Unbounded Contention Resolution in Multiple-Access Channels [PDF]
Algorithmica, 2011 A frequent problem in settings where a unique resource must be shared among users is how to resolve the contention that arises when all of them must use it, but the resource allows only for one user each time. The application of efficient solutions for this problem spans a myriad of settings such as radio communication networks or databases.

A novel mechanism for contention resolution in HFC networks
, 2003 The Medium Access Control (MAC) scheme proposed by DAVIC/DVB, IEEE 802.14 and DOCSIS for the upstream channel of Hybrid Fiber Coaxial (HFC) access networks is based on a mixable contention-based/contention-less time slot assignment. Contention-less slots
