并提出一种适用于该网络结构的快速二层切换协议, |
A new layer-II fast handoff protocol was designed for such network structure to deal with handoff issue in real-time services. |

以满足应急通信系统中终端的实时型业务数据传输对越区切换的严格要求,根据终端的移动速率自适应调整触发切换判决门限。 |
In this handoff protocol, the handoff trigger threshold is self-adaption based on the moving velocity of mobile terminals. |

研究了一种能量捕获协作中继网络, |
An energy capture cooperative relay network was studied. |

与传统协作中继网络不同,中继节点一般没有固定的能量供应但可以进行能量捕获。 |
Unlike traditional cooperative relay networks, the relay nodes generally did not have a fixed energy supply but could carry out energy capture. |

对于这种网络,一个自然的问题就是如何决定中继点是该进行能量捕获还是数据转发,以及如何选择中继节点以协助信息在源节点与目的节点间的传输。 |
For this network, a natural question was how to determine whether the relay nodes perform energy capture or data forwarding, and how to select the relay node to assist the information transmission between the source node and the destination node. |

基于这个问题,提出一种多中继节点选择方案,该方案根据中继节点当前时隙的能量来选择其操作。 |
Based on this problem, a multi-relay node selection scheme was proposed, which select the operation according to the energy of the current time slot of the relay node. |

在每个时隙中,满足电池阈值要求的中继节点会被选择进行协助传输。 |
In each time slot, the relay node that meet the battery threshold requirements was selected to assist in transmission. |

利用马尔可夫链对中继节点电池的充放电过程来进行建模化,得出该无线网络达到稳定状态时的中断概率以及吞吐率表达式, |
The Markov chain was used to model the charging and discharging process of the relay node battery,and the probability of interruption and throughput of the wireless network was obtained. |

并对使吞吐率最大,即网络中断概率最小时的电池阈值的取值进行求解。 |
And the value of the battery thresh-old when the throughput was maximized, that is, when the probability of network breakage was minimum was solved. |

最后,通过数值实验验证方案的优点。 |
Finally, the advantages of this scheme were verified by numerical experiments. |
