Abstract:

Opportunistic networks use the opportunity which generated by the nodes movement to transmit information. It can be widely used in the environment of data
sharing in a short distance due to properties of opportunitys self-organization and without a fixed communication infrastructure. However, the traditional routing algorithm in
opportunistic network does not take into account the characteristics of data sharing. So messages dissemination only can use the traditional forms like flooding. This paper
first analyzes the specific features and attributes of the data sharing opportunistic network, and puts forward the concept of anchor zone and the destination node clusters in
the process of messages dissemination. Furthermore, we propose a new scheduling algorithm based on the level the time to live of the message with different importance and
lifetime. Moreover, we put forward the new routing strategies through combining the data sharing network attributes with scheduling algorithm, so the message spread quickly and
efficiently in the network according to its anchor region and the destination node cluster. Finally, we verify the correctness and efficiency of the routing strategy by
simulation experiments.
