A Semantic-Associated Factor Graph Model for LiDAR-Assisted Indoor Multipath Localization [PDF]

open access: yesSensors
In indoor environments where Global Navigation Satellite System (GNSS) signals are entirely blocked, wireless signals such as 5G and Ultra-Wideband (UWB) have become primary means for high-precision positioning. However, complex indoor structures lead to

BA-MPCUBIC: Bottleneck-Aware Multipath CUBIC for Multipath-TCP [PDF]

open access: yesSensors, 2021
The Congestion Control Algorithm (CCA) in the Multipath Transmission Control Protocol (MPTCP) is fundamental to controlling the flow of data through multiple subflows (SF) simultaneously. The MPTCP CCA has two design goals: first, always ensure better throughput than single path TCP (SPTCP) flows, and second, collectively, MPTCP SFs going through a ...

The Disjoint Multipath Challenge: Multiple Disjoint Paths Guaranteeing Scalability

open access: yesIEEE Access, 2021
The multipath challenge is a research line in continuous development because of its multiple benefits, however, these benefits are overshadowed by scalability, which goes down considerably when the paths are multiple and disjoint.

Random Guessing for Beam Alignment: A Low Complexity Strategy for Reducing Blockage in mmWave Communications

open access: yesIEEE Access, 2022
High frequency (millimeter wave and higher) systems are being used for curb-to-home services and indoor networks with fixed transmitter and receivers. However, the environment between them can shift due to moving flora and fauna causing sudden blockages.

Adaptive algorithm for wireless data transmission (including images) based on SISO system and OFDM technique [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2018
The efficiency of wireless systems to transmit information in a complex interference situation is one of the main indicators of the effectiveness of the system, which can be characterized by the probability of an error in the transmitted message.
