Abstract: Contact probing process is an extremely energy-consuming process in Delay Tolerant Networks（DTNs）. In order to investigate the impact of energy consuming on the contact probing process in DTNs, the contact probing process based on the real mobility trace is modeled, and the single contact probing probability and the double contact probing probability are obtained when the contact probing interval is constant, respectively. Then, based on the proposed model, it is analyzed that the impact of energy consuming on the contact probing process under different situations. Finally, extensive real trace-driven simulations are conducted to validate the correctness of the proposed model.
