Research for delay tolerant network node similarity-based on social network

Social network is a special kind of network, and the relationship between nodes in social networks are used to evaluate a network of social-related strength. Network area is divided into multiple regions, as the network node has its own properties in the multiple regions, the use of node location, direction of movement, movement speed, active between the nodes to reflect the Multi-region Similarity. The Simulation shows the node of forwarding packet is based on the Multi-region Similarity of nodes, which would greatly improve the forwarding efficiency, and reduce the consumption of network resources at the same time. © 2013 by Binary Information Press.
