The introduction of intelligent devices with short range wireless communication techniques
has motivated the development of Mobile Ad hoc NETworks (MANETs) during the last few …

Delay tolerant networks (DTNs) may lack continuous network connectivity. Routing in DTNs
is thus challenging since it must handle network partitioning, long delays, and dynamic …

Intermittently connected mobile networks are wireless networks where most of the time there
does not exist a complete path from the source to the destination. There are many real …

Many DTN routing protocols use a variety of mechanisms, including discovering the meeting
probabilities among nodes, packet replication, and network coding. The primary focus of …

Underwater sensor networks are attracting increasing interest from researchers in terrestrial
radio-based sensor networks. There are important physical, technological, and economic …

Intermittently connected mobile networks are wireless networks where most of the time there
does not exist a complete path from the source to the destination. There are many real …

Mobile opportunistic networks are characterized by unpredictable mobility, heterogeneity of
contact rates and lack of global information. Successful delivery of messages at low costs …

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 …

Communication networks, whether they are wired or wireless, have traditionally been
assumed to be connected at least most of the time. However, emerging applications such as …

Because a delay tolerant network (DTN) can often be partitioned, the problem of routing is
very challenging. However, routing benefits considerably if one can take advantage of …
