Roteamento Anycast Em Redes Tolerantes a Atrasos E Desconexões

Delay and Disruption Tolerant Networks (DTNs) adopt the concept of intermittent networks that may suffer frequent disconnections, with the possibility of never have a connectivity end-to-end between the source and destination in a given period of time. Therefore, the design of protocols for those networks becomes a unique challenge. In this article, will be treated the routing for delivery anycast that is useful in situations where a host, applications or users want to find a host that supports a particular service, but if many servers support the service, any of these servers can be used. To help the development of anycast routing, the simulation of a DTN with four unicast routing algorithms was done, and the results showed some changes in the behavior of these algorithms depending on the conditions used in the simulation. 1
