A quick presentation about Funet WLAN roaming, eduroam in Finland and about Wireless Tampere, which is based on eduroam architecture and technologies. The presentation also contains a short clip from my Terena Networking Conference 2010 presentation about the implementation and the future development of the Finnish Top Level RADIUS roaming server.
DTN-Amazon: Digital/Social Inclusion in the Amazon RegionWaldir Moreira
DTN-Amazon is a project developed in a partnership between SITILabs and Federal University of Para (UFPA/Brazil) since 2011. The main goal is to promote digital/social inclusion in the Amazon region by bringing Internet access to remote, infrastructureless locations such as the the riverside communities nearby UFPA. The project has implemented middleware solutions that are actually being experimented in a 7-node testbed at UFPA.
This presentation was given in TecWeb 2013 on April 16th, 2013 at University Lusofona in Lisbon, Portugal.

Spatial Locality in Pocket Switched NetworksWaldir Moreira
The current Internet design falls short in scenarios characterized by intermittent connectivity and absence of supporting infrastructure. Pocket switched networking allows communication between portable handheld user devices in such environments through the store-carry-forward paradigm. This involves storing data in device memory, exploiting user movement to physically transport the data, and forwarding through available short-range wireless interfaces. In this regard, user devices can be leveraged as data mules for point-to-point communication in two main scenarios: (i) conveying data between major infrastructures in urban areas (e.g., transporting sensor data to gateways in smart cities); and (ii) extending wireless coverage to provide connectivity in developing regions (e.g., bridging user devices and remote Internet access points). User movement in such scenarios exhibit spatial locality, which is the preference to a geographical location than others. This feature influences the data transfer opportunities that exist between different sets of users. This paper investigates the impact of locality on routing in pocket switched networks by: (i) evaluating the performance of existing routing strategies for point-to-point communication over different degrees of locality; and (ii) providing insights towards enhancing routing performance for realizing the aforementioned application scenarios through locality awareness.
This presentation was given in the 10th IEEE WoWMoM Workshop on Autonomic and Opportunistic Communications 2016 (AOC 2016), on June 21st, 2016 in Coimbra, Portugal.
In this talk I give a brief summary of the goals associated with the RDA/CODATA working group on Summer Schools in Cloud computing that I gave to the ICT4D group at Royal Holloway.

CIMPL: A Public Safety Tool based on Opportunistic CommunicationWaldir Moreira
Public safety plays an important role in what concerns the social welfare of citizens, thus impacting their quality of life. There are different mechanisms (e.g., police, firefighters) in place to help citizens feel safe, and the citizens themselves may have a more proactive posture (e.g., neighborhood watch). The proposed Android application, called CIMPL, targets the willingness of these model citizens in engaging in public safety efforts and the capabilities of their mobile personal devices to improve social welfare. CIMPL allows users to opportunistically exchange public safety content among their devices. This content, produced by users, identifies potential hazard situations, and is used to duly notify the authorities involved in the maintenance of public safety.
This presentation was given in the 15th International Conference on Ad Hoc Networks and Wireless (AdHoc-Now 2016), on July 4th, 2016 in Lille, France.

Connecting the Dots: Integrating RADIUS to Network Measurement and MonitoringKarri Huhtanen
Nowadays data of the network usage is too often separated to various network components all around service provider network. Utilising RADIUS more efficiently is one approach to collect more data about network usage, combining it to network measurement, monitoring and management makes it even more efficient tool to use to get a real network situation and history overview.
Building city and nationwide Wi-Fi coverage via cooperationKarri Huhtanen
Building city and nationwide Wi-Fi coverage via cooperation presents the problem of building yet another overlapping citywide network instead of choosing cooperative approach to connect existing Wi-Fi networks via common policies, configurations and authentication decisions. The presentation promotes expanding eduroam(tm) model from academic world to regional, intercompany and government roaming.
Building secure, privacy aware, quality Wi-Fi coverage via cooperationKarri Huhtanen

Disobey 2024: Karri Huhtanen: Wi-Fi Roaming Security and PrivacyKarri Huhtanen
Karri Huhtanen's presentation about Wi-Fi Roaming Security and Privacy in Disobey 2024 on the 16th of February 2024 ( https://disobey.fi/2024/profile/disobey2024-154-wi-fi-roaming-security-and-privacy ).
Wi-Fi network security presentations are often about breaking the link level (radio) encryption or deploying evil twin Wi-Fi access points to perform man-in-the-middle attacks. This presentation focuses instead to the security and privacy in Wi-Fi roaming, offloading and federated networks, where there are different issues and vectors to utilise or defend against.

networks, open for other roaming partners and roaming
research as a part of ICT SHOK Future Internet Testbed
7. Wireless Tampere community
network
●
a cooperative open wireless community network for
companies, consumers, education and research institutions
●
based on the RADIUS based eduroam(tm) technology for
roaming
●
58 realms, 44220 roaming authentications/year (2009), all
major cities and education institutions at Tampere region,
roughly 900 access points (most of them in public places)
●
participates already in Funet WLAN roaming, interested to
roam with also other municipal, community and commercial
Wi-Fi networks

Future directions
• Encouraging organisations to adopt RadSec =>
do not even have to run Radiator, there exists
open source proxy solution radsecproxy from
UNINETT
• Able and willing to test DNS based discovery or
RadSec in general but in search for partners
• Would really like to see DNS based peer-to-peer
roaming replacing hierarchical model and inter-
federation roaming between commercial and
academic worlds
