| dc.description.abstract | In recent years, mobile devices have become more and more prosperous. Most of the previous mobile devices need to rely on various base stations, and the establishment of base stations requires a lot of resources and costs. Therefore, in recent years, many wireless network architectures that can be used without a base station have been proposed. The architecture is called Ad Hoc Network.
In a Ad Hoc Network, communication devices can rely on each other′s ability to transmit and receive data, and communicate in an environment with little or no base station. When a wireless communication device gains mobility, it is called Mobile Ad Hoc Network( MANET). When a vehicle is used as a node, it is called VANET (Vehicle Ad Hoc Network).
The VANET (Vehicular Ad Hoc Network) is a network with a highly mobile topology that allows cars to be 100 to 300 meters away from each other to form a large-scale network. This kind of network can communicate with each other in real time, share each other′s car conditions to achieve safe driving, prevent accidents and even provide entertainment services in the car.
However, most of the existing cluster routing algorithms only consider distance or pure energy. When applied to electric vehicles, it will cause higher energy loss, a decrease in the success rate of packet transmission, and a significant increase in end-to-end delay. It cannot provide excellent packet transmission. Therefore, in this thesis, a solution is proposed to improve the performance of transmitting packets by adding an energy header on the packet and changing the broadcast method of path creation. The former can use the total remaining energy of the path and the number of hops of the path is used to comprehensively consider which path is the best path. The latter can reduce the control packets used to find the path and reduce the waste of energy. Together, this method can increase the survival time of the path and increase the transmission of packets and success rate, and is suitable for higher speeds. | en_US |
