Study of a modeling method and a communication protocol for a wireless ad-hoc network with high mobility nodes

在车载自组织网络（VANET）中，由于每个通信节点的高移动性，网络连接频繁变化。它的移动性可以用来提高消息传递率，因为车辆作为这样的节点沿着道路行驶，它们的轨迹可以预测。在本研究中，我进行了以下工作，并取得了如下成果：基于高移动性节点的行为对VANET进行建模并分析其消息传递率；与邻近车辆合作开发GPS/GNSS定位；开发一种消息传递协议，其中网络连接由于具有不稳定电源模型的节点而频繁更改；在VANET中对摩托车作为通信节点进行建模和分析。

In vehicle ad hoc networks (VANET), the network connectivity is frequently changed due to the high mobility of each communication node. Its mobility can be utilized for improving the message delivery ratio because vehicles as such nodes go along roads and their trajectory can be predicted. In this research, I have conducted the following tasks and have achieved a result: modeling a VANET and an analysis of its message delivery ratio considering the behavior of such high mobility nodes; developing a cooperative GPS/GNSS positioning with neighboring vehicles; developing a message delivery protocol where the network connectivity is frequently changed due to nodes with an unstable power supply model; modeling and analyzing motorcycles as a communication node in VANET.
