A multiple-metric routing using the proactive Optimized Link State Routing (OLSR) protocol to improve quality of service is proposed. It is known that multiple-metric routing is an NP-complete problem, but the Analytic Hierarchy Process (AHP) and Pruning techniques are used to perform such routing, providing the best available routes based on the considered metrics. The performance of the propo...

Open Educational Resources (OER) and Massive Open Online Courses (MOOC) have not developed with an inherent capacity to attend to the needs of disabled students. In our research, we aim to understand the social, contextual and organisational issues behind these inadequacies. Through this, interventions and best practices can be developed to improve the

Wireless Sensor Networks (WSNs) have a broad application range in the area of monitoring and surveillance tasks. Among these tasks, disaster detection or prevention in environmental scenarios is one typical application for WSN. Disasters may for example be forest fires, volcano outbreaks or flood disasters. Here, the monitored events have the potential to destroy the sensor devices themselves. ...

decreasing water resources has made optimum water allocation in agriculture essential. planning optimum irrigation and crop production function considering accessible water and growing stage is an efficient approach to increase water productivity. studies have applied this approach to maximize crop production using the fao crop production method introduced in 1979. however, the fao introduced a...

Hamiltonian simulation is a promising application for quantum computers to achieve advantage. We present classical algorithms based on tensor network methods optimize circuits this task. show that, compared Trotter product formulas, the classically optimized can be orders of magnitude more accurate and significantly extend total time.

The Bε -tree File System, or BetrFS, (pronounced “better eff ess”) is the first in-kernel file system to use a write-optimized index. Write optimized indexes (WOIs) are promising building blocks for storage systems because of their potential to implement both microwrites and large scans efficiently. Previous work on WOI-based file systems has shown promise but has also been hampered by several ...

Nowadays, the location awareness becomes a ubiquitous requirement for several computing applications. The utilization of such knowledge in mobile ad hoc networks is primarily limited by the scarcity of their resources. In this paper, we propose two cartography gathering schemes (OLSR-SCGS and OLSR-ACGS) that make use of the seminal OLSR signaling in order to endue nodes participating in the MAN...

We present a mathematical framework for quantifying the impact of node mobility on the overhead of proactive routing protocols in mobile ad hoc networks (MANETs). We focus on MANETs in which nodes move randomly. The analytical model we introduce models signaling overhead as a function of stability of topology, and characterizes the statistical distribution of topology evolutions. Although we co...
