低占空比(low-duty-cycle,简称LDC)技术是当前延长无线传感器网络生命周期的最关键技术,为了有效延长机会网络生命周期,将低占空比技术引入机会网络,形成 LDC 机会网络.但是,现有机会网络路由算法不能很好地适应 LDC 环境,其性能会大幅度下降.为了解决该问题,提出一种基于能量感知的移动低占空比机会网络纠删编码算法E-EC.仿真实验结果表明,与现有的典型机会网络路由算法相比,E-EC算法在延长移动机会网络生命周期以及增加数据传输成功率等方面带来明显的性能提升.

Low-Duty-Cycle (LDC) is the most important technique in increasing the lifecycle of wireless sensor networks. This paper imports low duty cycle technology into opportunistic networks to extend the lifecycle of opportunistic networks effectively. However, the existing routing algorithms for opportunistic networks perform poorly in LDC environment. To solve this problem, this paper proposes an erasure-coding algorithm based on energy-aware (E-EC) for LDC opportunistic networks. Simulation results show that, compared with existing classical algorithms, E-EC algorithm achieves significant performance improvement in terms of life cycle and data success rate.
