The increase of connected devices and the constantly evolving methods techniques by attackers pose a challenge for network intrusion detection systems from conception to operation. As result, we see constant adoption machine learning algorithms systems. However, dataset used these studies has become obsolete regarding both background attack traffic. This work describes AB-TRAP framework that enables use updated traffic considers operational concerns enable complete deployment solution. is...
The Novel Enablers for Cloud Slicing (NECOS) project addresses the limitations of current cloud computing infrastructures to respond demand new services, as presented in two use-cases, that will drive whole execution project. first use-case is focused on Telco service provider and oriented towards adoption their large networks. second targeting use edge clouds support devices with low computation storage capacity. envisaged solution based a concept, Lightweight Slice Defined (LSDC), an...
Multipoint communication is an important requirement for many types of applications such as videoconferencing, IPTV and online radio. However, the division Internet in autonomous systems hinders widespread adoption traditional multicast protocols, which, using distributed algorithms, delay group control events processing. This paper proposes a clean-slate approach logically centralized based on programmable networks anticipated processing all routes from each possible source, aiming to...
VANETs benefit from Delay Tolerant Networks (DTNs) routing algorithms when connectivity is intermittent because of the fast movement vehicles. Multi-copy DTN spread message copies to increase delivery probability but increasing network overhead. In this work we apply machine learning reduce overhead by discriminating worst intermediate nodes for transmission copies. The scenario a VANET public buses that follow specific routes and schedules. This repetitive behavior creates an opportunity...
According to recent studies, unmanned aerial vehicles can play a game-changing part in cost reduction and speed increase address the last-mile delivery problem attend emergencies. Last-mile services are becoming more relevant, especially when times social distance is required. However, systemic view of how provide feasible solution enable this application as vertical market urban context still inexistent. Given scenario, article contributes by proposing cyber-physical system roadmap...
Summary Data abundance poses the need for powerful and easy‐to‐use tools that support processing large amounts of data. MapReduce has been increasingly adopted over a decade by many companies, more recently, it attracted attention an increasing number researchers in several areas. One main advantage is complex details parallel processing, such as network programming, task scheduling, data placement, fault tolerance, are hidden conceptually simple framework. supported mature software...
Unmanned Aerial Vehicle (UAV) swarm, also named drone has been the study object of many types research due to its potential improve applications such as monitoring, surveillance, and search missions. With several drones flying simultaneously, challenge is increase their level automation intelligence while avoiding collision, reducing communication with these entities, improving strategical organization accomplish a specific task. In this sense, we propose solution coordinate UAV swarm using...
Despite the significant advancements in drone sensory device reliability, data integrity from these devices remains critical securing successful flight plans. A notable issue is vulnerability of GNSS to jamming attacks or signal loss satellites, potentially leading incomplete To address this, we introduce SiaN-VO, a Siamese neural network designed for visual odometry prediction such challenging scenarios. Our preliminary studies have shown promising results, particularly flights under static...
This paper presents FlexForward, an approach for dynamically manage SDN data plane forwarding mechanisms. feature leverages flexibility in two aspects: (i) it provides a new management method, which topological infrastructure requirements are satisfied by the most appropriate mechanism, residing each managed network element; (ii) further decoupling between control and planes offering tableless support. As proof of concept, implementation with different methods is carried out Open vSwitch....
Drones can play a game-changing role in reducing both cost and time the context of last-mile deliveries.This paper addresses delivery problem from complex system viewpoint, where collective performance drones is investigated.We consider with tradable permit model (TPM) for airspace use.Typically, other research works regarding drones, fully cooperative centralized scenario contemplated.In our approach, due to TPM, agents (i.e.drones) need compete permits distributed manner.We simulate...
Since its inception in 2004, MapReduce has revealed as a paramount platform and disruptive technology for the execution of high performance applications that process very large volumes data. Hadoop is one most popular widely adopted open source implementation. Companies execute over hundreds or thousands machines every day spend efforts tuning optimization to reduce infrastructure costs. However, framework around 190 parameters which can be adjusted number different configurations...
An ambulance is the type of emergency vehicle that, in order, to accomplish its mission transporting patients critical condition hospitals, they must run as fast can through a city streets' maze. Hence, it necessary real-time system that could obtain anytime location. Moreover, should advice on best routes based speed and time for achieve target, given survival depends efficiency this service.
