Information-centric Networks (ICN) aims to improve content delivery by promoting the content as the protagonist of the network layer. By naming, routing, and forwarding named content directly on the network layer, ICN allows the same content to satisfy requests from different users, enabling innetwork caches to place contents strategically near the interested users. This characteristic is especially...
Harnessing the full power of the paradigm-shifting cognitive radio ad hoc networks (CRAHNs) hinges on solving the problem of time synchronization between the radios on the different stages of the cognitive radio cycle. The dynamic network topology, the temporal and spatial variations in spectrum availability, and the distributed multi-hop architecture of CRAHNs mandate novel solutions to achieve time...
The Information-centric Network (ICN) paradigm is an important initiative toward an Internet architecture more suitable for content distribution. The change it imposes by naming, routing, and forwarding content directly on the network layer empowers the architecture with several interesting characteristics, such as in-network caching. As contents are meaningful for different users, they can be opportunistically...
Network services in MANETs, such as resource location and distribution of connectivity information, deal with node mobility and resource constraints to support applications. The reliability and availability of these services can be assured by data management approaches, as replication techniques using quorum systems. However, these systems are vulnerable to selfish and malicious nodes, that intentionally...
Operational services in MANETs, such as resource location and distribution of connectivity information, deal with node mobility and resource constraints to support applications. The reliability and availability of these services can be assured by data management approaches, as replication techniques using quorum systems. However, these systems are vulnerable to selfish and malicious nodes, that intentionally...
Reliable storage supports different data sharing services, such as mobility and cryptographic key management and distributed naming. Mobile Ad hoc NETworks (MANETs) present issues in guaranteeing the consistency of data on concurrent read and write due to dynamism of nodes, the inexistence of a central control entity and support infrastructure. Probabilistic quorum systems, as PAN (Probabilistic Ad...
