OPPORTUNISTIC PROTOCOLS FOR DATA DISSEMINATION IN DELAY-TOLERANT NETWORKS

Description of research

As individual elements of any wireless network, communication devices with high mobility and intermittent connectivity may inconvenience the practicability of conventional networking approaches. Regardless of traditional end-to-end communication protocols, it is quite evident that basic intra- and/or inter-characteristics of the elements in such heterogeneous networks may take the advantage of novel opportunistic approaches. By this means, delay-tolerant networks (DTNs) is triggered as a new paradigm which serve an effectively operating environment over structured wireless networks, or even extreme terrestrial regions by isolating delay with message switching techniques between and within the networks. With the utilization of functionalities and characteristics of the networks, DTNs also profit by the mobility of the nodes of the network in which information belonging to any source is always tried to be disseminated over the environment as well as transmitted towards a given destination.

A wireless sensor network is inherently unpredictable due to factors like mobility, node variety, fluctuating radio channels or unpredictable communication paths from source to destination. We aim to focus on main challenges in DTNs by addressing extensive researches on large delay for transmissions resulting from either physical link properties or extended periods of network partitioning, routing capable of operating efficiently with frequently-disconnected, pre-scheduled, or opportunistic link availability, high link/packet error rates making end-to-end reliability difficult, heterogeneous underlying network technologies, and application structure and security mechanisms capable of limiting network access prior to data delivery in an environment where round-trip times may be very large or fail completely.
