Abstract American Sign Language (ASL) alphabet recognition using marker-less vision
sensors is a challenging task due to the complexity of ASL alphabet signs, self-occlusion of …

We define an opportunistic network as one type of challenged networks where network
contacts are intermittent or where link performance is highly variable or extreme. In such a …

Networking for challenged environments, or Delay-and Disruption-Tolerant Networking as it
is now most commonly referred to, has attracted great attention in the past few years by the …

Mobile Ad-hoc Network (MANET) routing protocols aim at establishing end-to-end paths
between communicating nodes and thus support end-to-end semantics of existing transports …

Opportunistic connections to the Internet from open wireless access points is now commonly
possible in urban areas. Vehicular networks can opportunistically connect to the Internet for …

Mobile Internet users have several options today including high bandwidth cellular data
services such as 3G, that may be the choice for many. However, the ubiquity and low cost of …

Delay-tolerant networking is used for communication in challenged environments such as
MANETs, in which links are unstable and end-to-end paths between communicating nodes …

Delay tolerant networking (DTN) allows endpoints to exchange information in networks
where end-to-end path may not exist at any given time. In this opportunistic model, routing …

In this paper, we address the challenges of content transfer in opportunistic networks, and
propose techniques to better facilitate data dissemination based on the characteristics of the …

Today, it is still hard to form an alternative network in a maritime environment besides using
costly satellite links because of the lack of wireless infrastructure at sea. In the TRITON …
