中文摘要： 无线多跳自组织网络在军事、应急通信、地震救灾等特殊领域，以及交通、智能家庭等物联网领域有着广阔的应用前景，得到了军方、工业界和学术界的广泛关注。传输调度方案设计是不同节点在干扰环境中互相通信的前提条件，因此传输调度的理论研究与设计是无线多跳自组织网络中一个非常重要的问题。与商用自组网不同，在军事、应急通信等应用中，自组网具有高动态、远距离、定向通信等特点。本研究拟针对高动态方向性多跳自组网的特点，构建无线信道-网络移动特性-网络感知-功率控制-传输调度联合优化架构，提出高动态方向性多跳自组网吞吐量与延时保证传输调度协议。我们还将研究高动态方向性自组网公平性、可靠性与网络效率之间的折中关系。最后，我们将在现有工程基础上设计实用的多频段无线多跳自组网试验平台，对提出的理论和协议进行验证和评测。

英文摘要： The wireless multi-hop ad hoc network is a very attractive technology for military, industry and academy, especially in the area of military communications, emergency communications, and Internet of Things such as transportation, intellengent building and so on. Transmission scheduling algorithms are important for each user in the network to communicate with each other correctly and efficiently. Thus, the theory, design and implementation of transmission scheduling is one of the most important aspects in the research of wireless multi-hop ad hoc networks. In military and/or emergency communications, the fundamental characteristics of wireless ad hoc networks are highly dynamic topology changes, very long communication distances, and direcational transmissions and receptions, which are different from those in commercial ad hoc networks. In this research, based on the aforementioned characteristics of wireless ad hoc networks designed for military and/or emergency communications, we firstly propose unified optimization framework of wireless channel, mobility, network sensing, power control and transmission scheduling. Secondly, we design scheduling algorithms that can support throughput and delay guarantees in the highly dynamic wireless multi-hop ad hoc networks with directional antennas. In addition, we investige the tradeoffs among network efficiency, reliabilty, and fairness. Finally, we will design the testbed of multi-channel wireless multi-hop ad hoc networks and verify the correctness and performance of our proposed algorithms.
