Summary:碩士 === 國立中興大學 === 電機工程學系所 === 99 === In a vehicular ad-hoc network, the topology may change frequently. Thus we want to find a way to reduce the frequent changes, and organize nodes effectively. To solve this problem, some trade-offs are made. The key design issue is how to make the topology stable quickly. This paper focuses on distributed topology control in order to reduce the rate of group member change, and avoid the unnecessary information exchange. Two methods are sequentially applied to choose the group members of each node: the first method is based on the concept of the cone-based method, which can exclude a lot of nodes quickly; the second method is based on the concept of the time-slot method, which can stabilize the network topology. The simulation results show that the proposed scheme can achieve effective topology management under certain scenarios.
