A Multi-language Platform for Generating Algebraic Mathematical Word Problems
Vijini Liyanage, Surangika Ranathunga
Existing approaches for automatically generating mathematical word problems are deprived of customizability and creativity due to the inherent nature of template-based mechanisms t…
An Energy Efficient D2D Model with Guaranteed Quality of Service for Cloud Radio Access Networks
Isuru Janith Ranawaka, Kasun T. Hemachandra, Tharaka Samarasinghe +1
This paper proposes a spectrum selection scheme and a transmit power minimization scheme for a device-to-device (D2D) network cross-laid with a cloud radio access network (CRAN). T…
A Discrete-Time Markov Chain Based Comparison of the MAC Layer Performance of C-V2X Mode 4 and IEEE 802.11p
Geeth P. Wijesiri, Jussi Haapola, Tharaka Samarasinghe
Vehicle-to-vehicle (V2V) communication plays a pivotal role in intelligent transport systems (ITS) with cellular-vehicle to everything (C-V2X) and IEEE 802.11p being the two compet…
Scalable High Performance SDN Switch Architecture on FPGA for Core Networks
Sasindu Wijeratne, Ashen Ekanayake, Sandaruwan Jayaweera +2
Due to the increasing heterogeneity in network user requirements, dynamically varying day to day network traffic patterns and delay in-network service deployment, there is a huge d…
Physical-Layer Security for Untrusted UAV-Assisted Full-Duplex Wireless Networks
Theshani Nuradha, Kasun T. Hemachandra, Tharaka Samarasinghe +1
The paper considers physical layer security (PLS) of an untrusted unmanned aerial vehicle (UAV) network, where a multitude of UAVs communicate in full-duplex (FD) mode. A source-ba…
Gated Recurrent Neural Network Approach for Multilabel Emotion Detection in Microblogs
Prabod Rathnayaka, Supun Abeysinghe, Chamod Samarajeewa +5
People express their opinions and emotions freely in social media posts and online reviews that contain valuable feedback for multiple stakeholders such as businesses and political…
