Performance Study of Opportunistic Network Based on Low Duty Cycle Technology

This paper imports Low Duty Cycle(LDC) technology into opportunistic networks for enlarging the life cycle of opportunistic network.The nodes encounter problem in LDC is studies.The effect on encounter probability of nodes and LDC opportunistic network with the change of node moving speed,communication range and duty cycle are analysed.Simulation results show that low duty cycle technology can significantly extend the life cycle of opportunistic network while losing a small number of meet opportunities.
