Uma nova política de gerencia de buffer para Redes Tolerantes ao Atraso e Desconexões baseada em relações sociais

Some types of Delay and Disruption Tolerant Networks (DTNs) need of humans help to send data between users. However, humans are socially selfishness and prefer to help users with whom they have a social relationship, fact that affects the network performance. Given the limited memory secondary space in the devices, the buffer management becomes a crucial factor to satisfactory network performance. This paper presents a novel buffer management policy for DTNs, based on social relationship strength between users. We evaluated this policy in conjunction with the Epidemic routing algorithm. The results show that this policy increases the delivery rate besides decreasing the average delay and the average number of hops in the evaluated scenario.
