Optimal and sub‐optimal rate and power allocation for random networks
Transactions on Emerging Telecommunications Technologies, Volume 34, Issue 4, April 2023., 2023 We consider the power and rate allocation for a transmission in a wireless network where the transmitter knows the channel state of the desired receiver but only knows the statistics of the interferes. While this scenario is often encountered in practice, and extremely important in dense networks, its optimal solution was not yet known.

Mitigating RF jamming attacks at the physical layer with machine learning
IET Communications, Volume 17, Issue 1, Page 12-28, January 2023., 2023 Abstract Wireless communication devices must be protected from malicious threats, including active jamming attacks, due to the widespread use of wireless systems throughout our every‐day lives. Jamming mitigation techniques are predominately evaluated through simulation or with hardware for very specific jamming conditions.

Throughput Analysis of Large Wireless Networks with Regular Topologies
EURASIP Journal on Wireless Communications and Networking, 2007 The throughput of large wireless networks with regular topologies is analyzed under two medium-access control schemes: synchronous array method (SAM) and slotted ALOHA. The regular topologies considered are square, hexagon, and triangle.

Stability of slotted ALOHA with spatial diversity [PDF]
IEEE International Conference on Communications, 2003. ICC '03., 2004 We consider the problem of stability of slotted ALOHA for a system consisting of N users communicating with a common receiver, which employs spatial diversity to receive multiple transmissions simultaneously. We introduce a general packet reception model to incorporate multiple packet receptions since the collision channel model is no longer valid in ...

Comparing Delay-Constrained ALOHA and CSMA: A Learning-Based Low-Complexity Approximate Approach
IEEE Open Journal of the Communications Society, 2021 Supporting delay-constrained traffic becomes more and more critical in multimedia communication systems, tactile Internet, networked control systems, and cyber-physical systems, etc. In delay-constrained traffic, each packet has a hard deadline.

Performance Enhancements for Asynchronous Random Access Protocols over Satellite [PDF]
, 2011 In this paper, a novel enhancement of the well known ALOHA random access mechanism is presented which largely extends the achievable throughput compared to traditional ALOHA and provides significantly lower packet loss rates. The novel mechanism, called

A novel RFID multi-tag anti-collision protocol for dynamic vehicle identification.
PLoS ONE, 2019 In order to obtain the information of the vehicle tags in adverse traffic conditions, we proposed a novel reservation framework named reservation to cancel idle-dynamic frame slotted ALOHA (RTCI-DFSA) algorithm.

Age of Information in Slotted ALOHA With Energy Harvesting [PDF]
GLOBECOM 2023 - 2023 IEEE Global Communications Conference, 2023 We examine the age of information (AoI) of a status update system that incorporates energy harvesting and uses the slotted ALOHA protocol. We derive analytically the average AoI and the probability that the AoI exceeds a given threshold. Via numerical results, we investigate two strategies to minimize the age of information (AoI): transmitting a new ...
