Performance and Reliability Analysis of Prioritized Safety Messages Broadcasting in DSRC With Hidden Terminals

open access: yesIEEE Access, 2020
In this paper, we design a mathematical model for performance and reliability evaluation of the IEEE 802.11p Enhanced Distributed Channel Access (EDCA) broadcast scheme in Dedicated Short-Range Communication (DSRC) with the presence of hidden terminals ...

A geometric design method for intersections with pre-signal systems using a phase swap sorting strategy.

open access: yesPLoS ONE, 2019
Conventional geometric design methods for pre-signal systems usually use the expected traffic demand, which may obtain a short sorting area distance and lead to frequent queue spillbacks due to stochastic traffic arrivals.

Hardware acceleration of number theoretic transform for zk‐SNARK

open access: yesEngineering Reports, EarlyView., 2023
An FPGA‐based hardware accelerator with a multi‐level pipeline is designed to support the large‐bitwidth and large‐scale NTT tasks in zk‐SNARK. It can be flexibly scaled to different scales of FPGAs and has been equipped in the heterogeneous acceleration system with the help of HLS and OpenCL.

Link Travel Time Estimation in Double-Queue-Based Traffic Models

open access: yesPromet (Zagreb), 2021
Double queue concept has gained its popularity in dynamic user equilibrium (DUE) modeling because it can properly model real traffic dynamics. While directly solving such double-queue-based DUE problems is extremely challenging, an approximation scheme ...

Fuzzy Set-Point Weight for PID Controller Based on Antlion Optimizer to Congestion Avoidance in TCP/AQM Routers

open access: yesIraqi Journal of Information & Communication Technology, 2020
: The delay in delivering packets and packets loss in computer networks is due to the problem of congestion in TCP/AQM routers, and to solve this crisis the TCP and AQM worked together.

A Fixed-Point Algorithm for Closed Queueing Networks [PDF]

open access: yes, 2007
In this paper we propose a new efficient iterative scheme for solving closed queueing networks with phase-type service time distributions. The method is especially efficient and accurate in case of large numbers of nodes and large customer populations.

Energy Utilization and Transmission Delay Optimization in Cox VANET networks [PDF]

open access: yesE3S Web of Conferences, 2022
Among the challenges in VANETs networks there is power control, which permits to achieve better permformance in terms of Signal to Interference plus Noise Ratio (SINR), Energy Efficiency (EE), Energy Utilization (EU),...

Scheduling a Make-To-Stock Queue: Index Policies and Hedging Points [PDF]

open access: yesOperations Research, 1996
A single machine produces several different classes of items in a make-to-stock mode. We consider the problem of scheduling the machine to regulate finished goods inventory, minimizing holding and backorder, or holding and lost sales costs. Demands are Poisson, service times are exponentially distributed, and there are no delays or costs associated ...

Queueing System with Potential for Recruiting Secondary Servers

open access: yesMathematics, 2023
In this paper, we consider a single server queueing system in which the arrivals occur according to a Markovian arrival process (MAP). The served customers may be recruited (or opted from those customers’ point of view) to act as secondary servers to ...
