Exploiting Information-centric Networking to Federate Spatial Databases

This paper explores the methodologies, challenges, and expected advantages related to the use of the information-centric network (ICN) technology for federating spatial databases. ICN services allow simplifying the design of federation procedures, improving their performance, and providing so-called data-centric security. In this work, we present an architecture that is able to federate spatial databases and evaluate its performance using a real data set coming from OpenStreetMap within a heterogeneous federation formed by MongoDB and CouchBase spatial database systems

A Taxonomy on Misbehaving Nodes in Delay Tolerant Networks

Delay Tolerant Networks (DTNs) are type of Intermittently Connected Networks (ICNs) featured by long delay, intermittent connectivity, asymmetric data rates and high error rates. DTNs have been primarily developed for InterPlanetary Networks (IPNs), however, have shown promising potential in challenged networks i.e. DakNet, ZebraNet, KioskNet and WiderNet. Due to unique nature of intermittent connectivity and long delay, DTNs face challenges in routing, key management, privacy, fragmentation and misbehaving nodes. Here, misbehaving nodes i.e. malicious and selfish nodes launch various attacks including flood, packet drop and fake packets attack, inevitably overuse scarce resources (e.g., buffer and bandwidth) in DTNs. The focus of this survey is on a review of misbehaving node attacks, and detection algorithms. We firstly classify various of attacks depending on the type of misbehaving nodes. Then, detection algorithms for these misbehaving nodes are categorized depending on preventive and detective based features. The panoramic view on misbehaving nodes and detection algorithms are further analyzed, evaluated mathematically through a number of performance metrics. Future directions guiding this topic are also presented

Information-Centric Networking in next-generation communications scenarios

Next-generation networking environments, characterized by the overlapping of wireless networks of different types, are emerging as a new and extremely interesting scenario. Their high dynamicity and heterogeneity present significant challenges from the communications perspective, which call for the adoption of new paradigms based on opportunistic and Information-Centric Networking (ICN) approaches. Applications operating in next-generation environments have peculiar characteristics that could benefit from ICN-based middleware solutions. This paper presents ICeDiM, a middleware we designed for ICN communications in next-generation scenarios, which builds on top of the innovative concept of Application-level Dissemination Channels (ADCs) with tunable permeability levels. A thorough and in-depth experimental evaluation of ICeDiM in a next-generation environment realistically simulated using ICeONE, a modified version of the well-known ONE simulator, demonstrates that our approach can achieve very good performance levels in terms of delivery ratio and network resource consumption
