Many of the existing opportunistic networking systems have been designed assuming a small number links per node and have trouble scaling to large numbers of potential concurrent communication partners. In the real world we often find wireless local area ...

In large-scale disaster scenarios, efficient triage management is a major challenge for emergency services. Rescue forces traditionally respond to such incidents with a paper-based triage system, but technical solutions can potentially achieve improved ...

The increasing trend on wireless-connected devices makes opportunistic networking a promising alternative to existing infrastructure-based networks. However, these networks offer no guarantees about connection availability or network topology. The ...

The Stream Control Transmission Protocol (SCTP) offers several distinct features which can be leveraged for Disruption or Delay Tolerant Networking (DTN). SCTP is able to handle an arbitrary number of independent streams in one connection---termed an ...

A 21-node low-power wireless mesh network is deployed in a peach orchard. The network serves as a frost event prediction system. On top of sensor values, devices also report network statistics. In 3 months of operations, the network has produced over 4 ...

Precision livestock farming and other agricultural applications are considered to have great potential to utilise the many benefits of IoT technology. It is however important to maintain low cost and energy consumption to make it feasible in a very ...

Next-generation hydrologic science and monitoring requires real-time, spatially distributed measurements of key variables including: soil moisture, air/soil temperature, snow depth, and air relative humidity. The SierraNet project provides these ...

In this work, we show how to use HINT, a real-time event-driven network emulator, to support the development process of opportunistic applications. In this demo, we use this emulator in conjunction with an example Android chat application to demonstrate ...

Many of today's popular online social networks are disconnected from their users' immediate social and physical context, which makes them poorly suited for supporting transient, on-purpose social communities of co-located users. We introduce the idea of ...

Network densification via small cells is considered as a key step to cope with the data tsunami. Caching data at small cells or even user devices is also considered as a promising way to alleviate the backhaul congestion this densification might cause. ...

Call Detail Records (CDRs) have been widely used in the last decades for studying different aspects of human mobility. The accuracy of CDRs strongly depends on the user-network interaction frequency: hence, the temporal and spatial sparsity that ...

Caching popular content at the edge of future mobile networks has been widely considered in order to alleviate the impact of the data tsunami on both the access and backhaul networks. A number of interesting techniques have been proposed, including ...

Information centric networking (ICN) is a proposal for a future internetworking architecture that is more efficient and scalable. While several ICN architectures have been evaluated for networks carrying web and video traffic, the benefits and ...

In IoT environments, a significant fraction of services can be expected to be relevant and contextualised to the physical area where data is generated. This is due to the typical strong bond between IoT devices and the physical environment where they ...

Bluetooth Low Energy (BLE) was designed as a low power alternative to classic Bluetooth. However, the use of BLE in dense, Internet of Things (IoT) deployments results in high collision rates and wasted energy. In response, we present an in-depth ...

This paper is motivated by the fact that modern cities are surprisingly vulnerable to large-scale emergencies, such as the recent terrorist attacks on Paris that resulted in the death of 130 people. Disaster shelters are one of the most effective ...

Opportunistic sensor networks typically rely on node mobility to monitor an area by collecting samples at different locations. In this paper we show how the mobility in combination with the periodic sampling of nodes causes large differences in the ...
