Shift-invariant protocol sequences for the collision channel without feedback

KW Shum, CS Chen, CW Sung… - IEEE Transactions on …, 2009 - ieeexplore.ieee.org
The authors consider collision channel without feedback in which collided packets are
considered unrecoverable. For each user, the transmission of packets follows a specific …

Safety-message broadcast in vehicular ad hoc networks based on protocol sequences

Y Wu, KW Shum, WS Wong… - IEEE Transactions on …, 2013 - ieeexplore.ieee.org
In vehicular collision avoidance systems, safety messages are broadcast by mobile users
periodically on the highway to all of their neighbors within hearing range. These safety …

DV-hop localization with protocol sequence based access

L Gui, X Huang, F **ao, Y Zhang, F Shu… - IEEE Transactions …, 2018 - ieeexplore.ieee.org

Protocol sequences for the multiple-packet reception channel without feedback

Y Zhang, YH Lo, WS Wong… - IEEE Transactions on …, 2016 - ieeexplore.ieee.org
Consider a time-slotted communication channel that is shared by K active users transmitting
to a single receiver. It is assumed that the receiver has the ability of the multiple-packet …

Event‐driven actuators: to zero or to hold?

G Guo, Z Lu, P Shi - … Journal of Robust and Nonlinear Control, 2014 - Wiley Online Library
This paper investigates networked control systems where a number of actuators are
involved but only a subset of them is assigned to be active at a time. The assignment of …

CRT sequences with applications to collision channels allowing successive interference cancellation

Y Chen, YH Lo, KW Shum, WS Wong… - IEEE Transactions on …, 2018 - ieeexplore.ieee.org
Protocol sequences are periodic zero-one sequences for the scheduling of packet

Transmission sequence design and allocation for wide-area ad hoc networks

WS Wong - IEEE Transactions on Vehicular Technology, 2013 - ieeexplore.ieee.org
In this paper, we examine the problem of designing and allocating transmission sequences
to users in a mobile ad hoc network that has no spatial boundary. A basic tenet of the …

A tight asymptotic bound on the size of constant-weight conflict-avoiding codes

KW Shum, WS Wong - Designs, Codes and Cryptography, 2010 - Springer
