In this paper, an opportunistic multi-copy two-hop routing algorithm is proposed for mobile social networks (MSNs) to minimize the expected data delivery delay, using local information. For each source-destination pair, the source dynamically maintains a forwarding set consisting of relay nodes. The forwarding set selection is based on the number of remaining message copies, as well as the number...
With the rapid growth of smartphone usage, mobile social networks (MSNs) are becoming increasingly popular. MSN can be considered as a type of delay tolerant network (DTN) which lacks continuous end-to-end connections between nodes, due to the node mobility and limited transmission range. Inspired by the homophily of social networks that friends are usually similar in characteristics, we present a...
Delay tolerant networks (DTNs) are a special type of wireless mobile networks which may lack continuous network connectivity. Multicast is an important routing function that supports the distribution of data to a group of users, a service needed for many potential DTNs applications. While multicasting in the Internet and mobile ad hoc networks has been studied extensively, efficient multicasting in...
