Opportunistic or delay-tolerant networks (DTNs) may be used to enable communication in
case of failure or lack of infrastructure (disaster, censorship, remote areas) and to …

In opportunistic networking, characterizing contact patterns between mobile users is
essential for assessing feasibility and performance of opportunistic applications. There has …

This work proposes an analytical model based on absorbing semi-Markov process for
predicting the expected pairwise delivery delay for single and multi-copy opportunistic …

This paper proposes an analytical model that captures the expected pairwise delivery delay
in an opportunistic network when the source can generate multiple copies of the message …

Capacity is difficult to estimate in sparse, intermittently-connected networks since timely
feedback and reliable signalling is usually unavailable. This paper proposes a resource …

Estimating end-to-end capacity is challenging in disruption-tolerant networks (DTNs)
because reliable and timely feedback is usually unavailable. This paper proposes a …

The last few decades have seen the performance and ubiquity of wireless networking
increase by leaps and bounds. This has had a great impact on day-to-day life, with people …

Nos últimos anos, a pesquisa na área de redes sem fio móveis tem crescido rapidamente. A
cada dia surgem novas demandas por protocolos e soluções para os mais diversos …

Delay-Tolerant Networks (DTNs) refer to mobile wireless networks that lack continuous
network connectivity among the nodes. To deal with such intermittent characteristics, DTNs …
