Color Multiset Codes based on Sunmao Construction

Wing Shing Wong, Chung Shue Chen, Yuan-Hsun Lo

We present results on coding using multisets instead of ordered sequences. The study is motivated by a moving object tracking problem in a sensor network and can find applications…

Analysis Methodology for Age of Information under Sequence Based Scheduling

Fang Liu, Wing Shing Wong, Yuan-Hsun Lo +2

We focus on the Age of Information (AoI) performance in a system where each user generates packets periodically to send to a common access point (AP) for status updating. To avoid…

Multiset Combinatorial Gray Codes with Application to Proximity Sensor Networks

Chung Shue Chen, Wing Shing Wong, Yuan-Hsun Lo +1

We investigate coding schemes that map source symbols into multisets of an alphabet set. Such a formulation of source coding is an alternative approach to the traditional framework…

The Undirected Optical Indices of Trees

Yuan-Hsun Lo, Hung-Lin Fu, Yijin Zhang +1

For a connected graph , an instance is a set of pairs of vertices and a corresponding routing is a set of paths specified for all vertex-pairs in . Let $\mathfrak{R}_…

New CRT sequence sets for a collision channel without feedback

Yijin Zhang, Yuan-Hsun Lo, Kenneth W. Shum +1

Protocol sequences are binary and periodic sequences used for deterministic multiple access in a collision channel without feedback. In this paper, we focus on user-irrepressible (…

Achieving Zero-Error Capacity 1 for a Collision Channel Without Feedback

Yijin Zhang, Yi Chen, Yuan-Hsun Lo +1

The collision channel without feedback (CCw/oFB) model introduced by Massey and Mathys, depicts a scenario in which M users share a thermal noise-free communication channel with ra…

The Global Packing Number for an Optical Network

Yuan-Hsun Lo, Yijin Zhang, Wing Shing Wong +1

The global packing number problem arises from the investigation of optimal wavelength allocation in an optical network that employs Wavelength Division Multiplexing (WDM). Consider…

Partially user-irrepressible sequence sets and conflict-avoiding codes

Yuan-Hsun Lo, Wing Shing Wong, Hung-Lin Fu

In this paper we give a partial shift version of user-irrepressible sequence sets and conflict-avoiding codes. By means of disjoint difference sets, we obtain an infinite number of…

Optimal strongly conflict-avoiding codes of even length and weight three

Yijin Zhang, Yuan-Hsun Lo, Wing Shing Wong

Strongly conflict-avoiding codes (SCACs) are employed in a slot-asynchronous multiple-access collision channel without feedback to guarantee that each active user can send at least…
