Human Activity Optimal Cooperation Objects Selection Routing Scheme in Opportunistic Networks Communication

There are some important features of opportunistic networks such as mobility of nodes, randomness of information transmission and no links in transmission. These features are similar with the information transmission among human beings in social activities in which people choose the objects they need to transmit information according to the situation of information sending and receiving. Traditional methods in opportunistic networks can not receive good result in the application of social network since the neglecting of societal and subjectivity of human beings. Thus, this paper suggests a routing scheme: Optimal Cooperation Objects Selection Routing in opportunistic networks based on the features of the opportunistic network. In this scheme, dependability ratio, usability ratio and weight factor are counted as weight in the human activity topology to get the optimal cooperation objects. This scheme is proved as a better method by the simulation compare with the traditional methods in opportunistic networks.
