An Implementation of Voice over the Cognitive Packet Network [PDF]

arXiv, 2014
Voice over IP (VOIP) has strict Quality of Service (QoS) constraints and requires real-time packet delivery, which poses a major challenge to IP networks. The Cognitive Packet Network (CPN) has been designed as a QoS-driven protocol that addresses user-oriented QoS demands by adaptively routing packets based on online sensing and measurement.

Performance Analysis of Bio-Inspired Routing Protocols based on Random Waypoint Mobility Model [PDF]

Defence S & T Technical Bulletin, Science & Research Technology Institute for Defence (STRIDE), Vol. 5, No. 2, November 2012, pp. 114-134, ISSN: 1985-6571, 2013
A mobile ad hoc network (MANET) is a non-centralised, multihop, wireless network that lacks a common infrastructure and hence it needs self-organisation. The biggest challenge in MANETs is to find a path between communicating nodes, which is the MANET routing problem.

An Empirical Study of Customer Spillover Learning about Service Quality [PDF]

arXiv, 2016
"Spillover" learning is defined as customers' learning about the quality of a service (or product) from their previous experiences with similar yet not identical services. In this paper, we propose a novel, parsimonious and general Bayesian hierarchical learning framework for estimating customers' spillover learning.

Quality of Service Support on High Level Petri-Net Based Model for Dynamic Configuration of Web Service Composition [PDF]

arXiv, 2012
Web services are widely used thanks to their features of universal interoperability between software assets, platform independent and loose-coupled. Web services composition is one of the most challenging topics in service computing area. In this paper, an approach based on High Level Petri-Net model as dynamic configuration schema of web services ...

Estimation of Time Delay caused by Point Geometry in Public Transport [PDF]

arXiv, 2018
Travel time prediction is a well-renowned topic of research. It is primarily influenced by traffic congestion, road conditions and route geometry. Among them route geometry at any point is not investigated enough to find a sound spatial dynamics of timing delays and quality of public transport.

Shaping Rewards, Shaping Routes: On Multi-Agent Deep Q-Networks for Routing in Satellite Constellation Networks [PDF]

arXiv
Effective routing in satellite mega-constellations has become crucial to facilitate the handling of increasing traffic loads, more complex network architectures, as well as the integration into 6G networks. To enhance adaptability as well as robustness to unpredictable traffic demands, and to solve dynamic routing environments efficiently, machine ...

Dynamic Directional Routing of Freight in the Physical Internet [PDF]

arXiv
The Physical Internet (PI) envisions an interconnected, modular, and dynamically managed logistics system inspired by the Digital Internet. It enables open-access networks where shipments traverse a hyperconnected system of hubs, adjusting routes based on real-time conditions.

Pipe Routing with Topology Control for UAV Networks [PDF]

arXiv
Routing protocols help in transmitting the sensed data from UAVs monitoring the targets (called target UAVs) to the BS. However, the highly dynamic nature of an autonomous, decentralized UAV network leads to frequent route breaks or traffic disruptions.

Semi-on-Demand Off-Peak Transit Services with Shared Autonomous Vehicles -- Service Planning, Simulation, and Analysis in Munich, Germany [PDF]

arXiv
This study investigates the implementation of semi-on-demand (SoD) hybrid-route services using Shared Autonomous Vehicles (SAVs) on existing transit lines. SoD services combine the cost efficiency of fixed-route buses with the flexibility of on-demand services.

A hybrid memetic-ANS optimization algorithm for the home health care and home care routing and re [PDF]

arXiv
This paper addresses a realistic home health care and home care (HHC\&HC) problem which has become increasingly complex in the face of demographic aging and post-COVID-19 disruptions. The HHC\&HC sector, as the essential component of modern health care systems, faces unique challenges in efficiently scheduling and routing caregivers to meet the rising ...
