Analysis of Multi-GNSS Multipath for Parameter-Unified Autocorrelation-Based Mitigation and the Impact of Constellation Shifts

open access: yesRemote Sensing
Multipath effects can significantly reduce the accuracy of GNSS precise positioning. Traditional methods, such as sidereal filtering and grid-based approaches, attempt to model and mitigate these errors by leveraging the spatial autocorrelation of ...

Ghost Removal from Forward-Scan Sonar Views near the Sea Surface for Image Enhancement and 3-D Object Modeling

open access: yesRemote Sensing
Underwater sonar is the primary remote sensing and imaging modality within turbid environments with poor visibility. The two-dimensional (2-D) images of a target near the air–sea interface (or resting on a hard seabed), acquired by forward-scan sonar ...

An Overview of Multipath TCP.

open access: yeslogin Usenix Mag., 2012
TCP has remained mostly unchanged for 20 years, even as its uses and the networks on which it runs have evolved. Multipath TCP is an evolution of TCP that allows it to run over multiple paths transparently to applications. In this article, we explain how Multipath TCP works, and why you should want to start using it.

Detecting changes in along-path HF propagation during the April 2024 total solar eclipse with radio amateurs and low-cost instrumentation

open access: yesFrontiers in Astronomy and Space Sciences
The total solar eclipse of April 8, 2024 presented a uniquely favorable circumstance for radio science. The Moon’s shadow passed near Canadian time standard station CHU, which transmits in the high frequency (HF, i.e., 3–30 MHz) band.

Multipath traffic splitting algorithm based on adaptive granularity

open access: yesTongxin xuebao, 2015
Aiming at the dilemma between load balancing and packet reordering in multipath routing,an adaptive dynamic multipath traffic splitting(ADTS) algorithm was proposed.The algorithm classified Internet flows into two categories:the aggressive and the normal

Secure and Efficient Multicast Content Distribution

open access: yesIEEE Access
This paper proposes a multicast content distribution method over quantum key distribution (QKD) networks that improves delivery latency and resilience to link bandwidth limitations through mesh network design, while also contributing to reduced key ...
