摘要/Abstract

摘要： 为延长机会网络生命周期，将低占空比技术引入到机会网络，研究低占空比环境下节点相遇的概率问题。分析节点移动速度、通信半径、占空比等参数的变化对于节点相遇概率和低占空比机会网络生命周期的影响。仿真实验结果表明，低占空比机会网络能够在损失少量节点相遇机会的前提下，大幅延长网络生命周期。

关键词: 低占空比技术, 机会网络, 物理相遇, 逻辑相遇, 相遇概率

Abstract: 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.

Key words: Low Duty Cycle(LDC) technology, opportunistic network, physical encounter, logical encounter, encounter probability
