Binary decision-based collaborative spectrum sensing in infrastructure-less cognitive radio network

Roshni Rajkumari, Ningrinla Marchang
Computer Science and Engineering Deaprtment, NERIST, Arunachal Pradesh, India

Abstract Collaborative spectrum sensing (CSS) plays a vital role in achieving accurate spectrum sensing results in a cognitive radio network (CRN). However, CSS in infrastructure-less CRNs is a challenging task as there is no central authority which aggregates individual sensing reports to take a final decision. Hence, it becomes the responsibility of each node to aggregate sensing reports of other nodes to take the final decision. Towards this end, we present two collaborative spectrum sensing techniques for infrastructure-less CRN based on message passing.» Read the summary

Time-constrained anycast routing under short contact duration in delay-tolerant networks

Tuan Le, Mario Gerla

Department of Computer Science, UCLA, Los Angeles, CA, USA

Abstract Delay-tolerant networks (DTNs) are sparse mobile ad hoc networks, in which there is typically no complete path between the source and destination. Anycast is an important group communication paradigm for numerous DTN applications such as resource discovery and information exchange in emergency or crisis situations.» Read the summary

Cloud-based federated identity for the Internet of Things

Paul Fremantle, Benjamin Aziz

School of Computing, University of Portsmouth, Portsmouth, UK

Abstract The Internet of Things (IoT) has significant security and privacy risks. Recent attacks have shown that not only are many IoT devices at risk of exploit, but those devices can be successfully used to attack wider systems and cause economic damage.» Read the summary

Abstract A large number of access points (APs) may be required to provide network coverage in a given environment. However, a non-optimized deployment of these APs can reduce the network performance significantly due to the excessive interference.» Read the summary

Abstract Given a graph with weights on the edges, a set of origin and destination pairs of nodes, and two integers L ≥ 2 and k ≥ 2, the k-node-disjoint hop-constrained network design problem is to find a minimum weight subgraph of G such that between every origin and destination there exist at least k node-disjoint paths of length at most L.» Read the summary

Improving spectrum efficiency in self-organized femtocells using learning automata and fractional frequency reuse

Maryam Nasr-Esfahani, Behrouz Shahgholi Ghahfarokhi
Department of Information Technology Engineering, Faculty of Computer Engineering, University of Isfahan, Isfahan, Iran

Abstract Deploying heterogeneous networks (HetNets) and especially femtocell technology improves indoor cell coverage and network capacity. However, since users install femtocells which usually reuse the same frequency band as macrocells, interference management is considered a main challenge. Recently, fractional frequency reuse (FFR) has been considered as a way to mitigate the interference in traditional as well as heterogeneous cellular networks.» Read the summary
