We study three related problems on unicast routing in Disruption-Tolerant Networks (DTNs), i.e., resource-challenged networks where contemporaneous end-to-end connectivity cannot be assumed. We particularly focus on mobility-induced DTNs with opportunistic contacts.are shown to improve block delivery delay versus transmissions overhead trade- off due to its increased randomness . ... a low-power, short range radio ( 100m, 19.2Kbps) for peer-to-peer communication, and only have 640KB of user- accessible FLASH RAM memory. ... buffer constraints, several recent works [61, 18, 12] have addressed transmission scheduling and buffer management problems.
