Social characteristics based multiple dimensional routing protocol in human associated delay tolerant networks

© The Author(s) 2015. This chapter introduces how to use multiple dimensional social attributes to improve data forwarding performance in human associated delay tolerant networks. As mobile nodes in these human associated DTNs are carried by humans, data forwarding processes are determined by human social behaviors [1]. If a node has two or more social attributes, it can be treated as a social hub (popular nodes with many social attributes), where characteristics with other nodes are shared in the overlapping area of the attributes.
