Link duration is a main factor in determining the transmission capacity between two encounter nodes in delay-tolerant networks (DTNs). Existing research on DTN transmission capacity usually assumes that a node can immediately discover the nodes that move into its transmission range. Under this assumption, the link duration in DTNs is determined by the moving speed and transmission distance of encounter...
In this paper, we investigate sophisticated mobility models that can be useful for researches in Delay-Tolerant Mobile Networks. Our research is based on the observation of existing movement traces with several simplifications for network tractability. First, we present a continuous Markovian mobility model, where mobile nodes stay at one location or move from locations to locations according to exponential...
Delay-tolerant networks (DTN) have the capacity to interconnect devices in roomy regions unlike traditional networks. Based on common sense, the more similar the mobility pattern of nodes, the more stable their relative positions, which results in a connection between them with a longer duration In this paper, a novel routing scheme using the similarity degree of mobility pattern is proposed to optimize...
