| Popis: | In this paper we propose a service advertisement dissemination mechanism for opportunistic social networks,which is used to solve the problem of the inefficiency of the central service registry incurred by node mobility and topology instability.We analyze service social characteristic showed in opportunistic social networks,and propose the concept of service social context and its measure method.Then we suggest a social context based service advertisement dissemination mechanism,which estimates a user's interest degree with a service in terms of service industry relevancy in order to select an advertising destination.Calculating utility by reliability and activeness and predicting the probability of meeting with a service industry by industry spatio-temporal relationship of coexistence,our approach selects a node to be an advertisement agent dynamically.Furthermore,we evaluate our approach's performance using a mobility model based on a social network validated with real human mobility traces.The experimental analyses are conducted and demonstrated the effectiveness and efficiency of our approach. |
