Abstract:

The centrality is used as routing metric in delay tolerant networks, which makes a part of nodes suffer from great traffic loads. A socialbased load aware routing algorithm is proposed to resolve this problem. The two social metrics of the nodes, betweenness centrality and the similarity, and the node’s load status are used to select relay nodes, which could avoid serious congestion in the nodes that have stronger ability of disseminating messages and could balance traffic load. Simulation results show that the proposed algorithm could increase the message delivery ratio and reduce network overhead.
