In recent years, the Vehicular Named Data Network (VNDN) architecture has been proposed to face performance and reliability challenges from IP/host centric Ad hoc Networks. The constant mobility of nodes in such networks can result rapid flooding unsatisfied interest packets thus leading network overloads. this article, we LSIF, a Link Stability-based Interest Forwarding strategy that relies on predictions link durations reduce number data packets. simulation results revealed LSIFs benefits....
Network Slicing (NS) is an essential technique extensively used in 5G networks computing strategies, mobile edge computing, cloud and verticals like the Internet of Vehicles industrial IoT, among others. NS foreseen as one leading enablers for 6G futuristic highly demanding applications since it allows optimization customization scarce disputed resources dynamic, clients with distinct application requirements. Various standardization organizations, 3GPP's proposal new generation...
The communication network context in actual systems like 5G, cloud and IoT (Internet of Things), presents an ever-increasing number users, applications services that are highly distributed with distinct heterogeneous communications requirements. Resource allocation this requires dynamic, efficient customized solutions Bandwidth Allocation Models (BAMs) alternative to support new trend. This paper proposes the BAMSDN (Bandwidth Model through Software-Defined Networking) framework dynamically...
In order to make recommendations users about the potential performance of advanced Internet applications - in scope network monitoring it is not sufficient just analyze metrics: should be also considered information concerning application type, traffic generated, and user profile. present paper, we propose a new approach for based on use an expert system. The system will infer from domain ontology named MonONTO. This amasses main concepts their relationships following sub-domains: quality...
In wireless networks, the Named Data Networking (NDN) architecture maximizes contents' availability throughout multiple network paths based on multicast-based communication combined with stateful forwarding and caching in intermediate nodes. Despite its benefits, downside of resides packet flooding not efficiently prevented by current strategies mainly associated native or malicious packets from Interest Flooding Attack (IFA). This work introduces iFLAT, a multicriteria-based strategy for...
Named Data Networking (NDN) is a new network architecture based on the content-based model that has fundamental differences to legacy path-based model. The first focused content itself, and latter focuses location of data. Both models provide different benefits end-user network, but they often cannot inter-operate due their significant design differences. Therefore, we propose protocol, both named NDN-Fab, allow inter-operation between architectures. NDN-Fab Fabric allows edge operate with...
BEEP is an energy-efficient strategy for data center networks (DCNs) based on a fat-tree topology. This combines multipaths and the global overview offered by software-defined (SDNs) to balance energy efficiency, equipment redundancy levels, DCN performance. implemented in OpenFlow network with enabled using Multipath TCP (MPTCP). Experimental results different variations of topology levels show gains savings 30-45 percent. Additionally, achieves better available bandwidth usage, because...
In-network cache architectures, such as Information-centric networks (ICNs), have proven to be an efficient alternative deal with the growing content consumption on networks. In caching networks, any device can potentially act a node. practice, real may employ different replacement policies by The reason is that vary in efficiency according unbounded context factors, size, request pattern, distribution popularity, and relative location. lack of suitable for all nodes scenarios undermines use...
Network densification by small cell networks has become the main alternative for mobile network operators to deal with an ever-increasing traffic growth. In this context, Named Data Networking (NDN), evolution of Content-Centric (CCN), emerges as improve data offloading promotion in-network caching. paper, we propose a user clustering scheme that takes advantage affinity among users respect frequency content requisition and common interest more efficient edge The proposed strategy is...

We present NDN for Inter-Vehicle Communication (NDN4IVC) framework simulating realistic VANET applications over the architecture. The project uses two popular simulators in literature simulation, network simulator ns3, with ndnSIM module installed, and SUMO, a urban mobility. NDN4IVC allows real-time bidirectional communication between SUMO ns3 to support more data about road traffic vehicular
Some of current Information-centric cellular networks strongly rely on clustering techniques to group users with similar preferences or behavior and assign them a common base station. As result, the most useful contents are kept near users, thereby alleviating backhaul bottlenecks. Despite performance gains, such strategies frequently adopt same replacement policy, irrespectively users' profile. This paper presents simulation-based study that evaluates cache policies through clusters formed...
Over the years, network monitoring tools have evolved to keep pace with advances in networking technologies and paradigms, such as virtualization softwarization, more recently, data plane programmability. However, there been few regarding user interfaces interactions management systems. In this paper, an investigation based on human-computer interaction perspective is presented improvements usability aspects of are proposed. First, we conducted a survey capture general information from...
Routing, forwarding strategy, and dataset synchronization (sync) are three well-known components of Named Data Networking (NDN). This poster reports a work-in-progress evaluation on the relationship between routing, sync, especially for scenarios with ad hoc mobile conditions intermittent connectivity.
