Traffic-Estimation-Based Low-Latency XGS-PON Mobile Front-Haul for Small-Cell C-RAN Based on an Adaptive Learning Neural Network

open access: yesApplied Sciences, 2018
In this paper, we propose a novel method for low-latency 10-Gigabit-capable symmetric passive optical network (XGS-PON) mobile front-haul for small cell cloud radio access network (C-RAN) based on traffic estimation. In this method, the number of packets

Affordance-based individuation of junctions in Open Street Map

open access: yesJournal of Spatial Information Science, 2012
We propose an algorithm that can be used to identify automatically the subset of street segments of a road network map that corresponds to a junction. The main idea is to use turn-compliant locomotion affordances, i.e., restricted patterns of supported ...

Efficient Geo-Computational Algorithms for Constructing Space-Time Prisms in Road Networks

open access: yesISPRS International Journal of Geo-Information, 2016
The Space-time prism (STP) is a key concept in time geography for analyzing human activity-travel behavior under various Space-time constraints. Most existing time-geographic studies use a straightforward algorithm to construct STPs in road networks by ...

Sensor Networks For Smart Roads [PDF]

open access: yesFourth Annual IEEE International Conference on Pervasive Computing and Communications Workshops (PERCOMW'06), 2006
This paper proposes the use of a wireless sensor network of "cat's eye" augmented with embedded processing, communication, and sensing capabilities to monitor vehicle behaviour on augmented roads. The primary goal of the system is to provide drivers with early warning of potentially dangerous situations that may arise.
