Minimizing File Transfer Time in Opportunistic Spectrum Access Model


By: J. Hu n, V. Doshi n & D. Eun n

author keywords: Delays; Throughput; Sensors; Switches; Mathematical models; Vehicle dynamics; Computational modeling; Opportunistic spectrum access; file transfer problem; minimum transfer time; shortest path problem
TL;DR: This work explicitly considers minimizing the file transfer time for a given file in a set of heterogeneous-rate Bernoulli channels, showing that max-throughput policy doesn't minimize file transferTime in general. (via Semantic Scholar)

Opportunistic Spectrum Access: Does Maximizing Throughput Minimize File Transfer Time?

2021 19th International Symposium on Modeling and Optimization in Mobile, Ad hoc, and Wireless Networks (WiOpt).

By: J. Hu n, V. Doshi n & D. Eun n

Contributors: J. Hu n

TL;DR: This work formulate a mathematical framework for the static policy, and extend to dynamic policy by mapping the file transfer problem to the stochastic shortest path problem, and analyzes the performance of the proposed static optimal and dynamic optimal policies over the policy that maximizes long-term throughput.

Performance Analysis and Improvement on DSRC Application for V2V Communication


By: L. Cao*, H. Yin*, J. Hu n & L. Zhang*

author keywords: V2V; DSRC; IEEE 802.11p; DCF; MAC design
TL;DR: The Semi-persistent Contention Density Control (SpCDC) scheme is developed to improve the DSRC performance and shows that the packet delivery ratio in SpCDC scheme increases more than 10% compared with IEEE 802.11p in heavy vehicle load scenarios. (via Semantic Scholar)
