Delay Tolerant Networks (DTNs) are characterized by node mobility and partitioned network topology, extremely long delivery latency, etc. Consequently, the traditional ad-hoc routing algorithms cannot work well in DTNs. In order to provide effective communication services in DTNs, in this paper, we propose an adaptive routing based on Node Performance and Encountering Probability (NPEP). NPEP chronologically...
Social Delay Tolerant Networks (SDTNs) are a special kind of Delay Tolerant Network (DTN) that consists of a number of mobile devices with social characteristics. The current research achievements on routing algorithms tend to separately evaluate the available profit for each prospective relay node and cannot achieve the global optimal performance in an overall perspective. In this paper, we propose...
Many Delay Tolerant Networks (DTNs) applications need multicast service, thus making efficient multicast communication support essential. In this paper, we propose a Probability-based Adaptive Multicast Routing scheme (PAMR) to address the challenges of intermittent link connectivity and frequent partitions in DTNs. PAMR relies on node encounter histories rather than the global knowledge or the summary...
