Abstract

Abstract: In the opportunistic network，nodes often be in the long disconnected state.Therefore，how to design a effective node wake-up scheduling pattern and keep the existing network connectivity are important issue.This paper proposes an opportunistic network wake-up scheduling policy，referred as ONWPM.The policy studies the relationship of key parameters in wake-up scheduling mechanism.Moreover，ONWPM controls the wake-up period intervals to ensure the effective data throughput of node.The simulation results show that this policy can reduce the power consumption of node under the premise of effective data delivery ratio and has good adaptability with opportunistic network.

摘要： 在机会网络中，节点经常处于较长时间的互不连通状态，因此如何设计有效的节点唤醒调度模式并确保不破坏网络现有的连通性是一个重要问题。提出了一种机会网络节点唤醒调度策略：ONWPM。该策略对唤醒调度机制中的关键参数关系进行研究，以确保数据有效传输量为目标，并基于此对唤醒周期间隔长度进行控制。仿真实验结果表明，ONWPM在保证节点有效数据发送性能的前提下，节省了节点消耗的能量并对机会网络有着较好的适应性。
