Age of Information: A New Concept, Metric, and Tool
In an increasingly networked world in which information is becoming increasingly actual, how can a system know with certainty just how fresh the information on a remote system is? Much work has been… Expand
RERUM: Building a reliable IoT upon privacy- and security- enabled smart objects
TLDR
The Internet of Things (IoT) provides a platform for the interconnection of a plethora of smart objects. Expand
Age of information of multiple sources with queue management
TLDR
We consider a system of multiple sources generating status update packets, which need to be sent by a single transmitter to a destination over a network. Expand
Allocation of Heterogeneous Resources of an IoT Device to Flexible Services
TLDR
We prove the NP-completeness of the problem and develop two algorithms to approximate the optimal solution for big instance sizes. Expand
Adjacent channel interference in 802.11a is harmful: Testbed validation of a simple quantification model
TLDR
Wireless LAN radio interfaces based on the IEEE 802.11a standard have lately found widespread use in many wireless applications. Expand
Optimization of Free Space Optical Wireless Network for Cellular Backhauling
TLDR
We present a novel integer linear programming model to approach optimal FSO backhaul design, guaranteeing $K$-disjoint paths connecting each node pair. Expand
Adjacent channel interference in 802.11a: Modeling and testbed validation
In this work we utilize the model for calculation of the interference power by partially overlapping channels and combine it with the signal to interference plus noise (SINK) criterion for signal… Expand
Age and value of information: Non-linear age case
TLDR
We consider a real-time status update system consisting of a source-destination network. Expand
Cognitive radio inspired M2M communications
TLDR
The Internet of Things (IoT) presents itself as one of the basic pillars of the Future Internet. Expand
Minimum-Time Link Scheduling for Emptying Wireless Systems: Solution Characterization and Algorithmic Framework
TLDR
We consider a set of transmitter-receiver pairs, or links, that share a wireless medium and address the problem of emptying backlogged queues with given initial size at the transmitters in minimum time. Expand
