Parts of these wireless technologies will be deployed in vehicular mobile networks. In vehicular networks, the power saving might not be the major problem, but the wireless resources are scarce. Therefore, how to make efficient use of wireless bandwidth is one of the most important issues in vehicular networks. Generally, header compression can be used with packet aggregation to make more efficient use of wireless bandwidth. Header compression reduces the waste of the header size, while packet aggregation reduces the number of packets. Unfortunately, packet aggregation might increase the end-to-end delay in multi-hop vehicular environment. On the other hand, routing path might change frequently due to the high-speed and high-mobility characteristics in vehicular networks. In the literature, a solicitation-based MAC protocol is used for solving dramatic path change due to high mobility and the lack of association in IEEE 802.11p. The goal of this thesis focuses on header compression and packet aggregation in vehicular networks. We integrate a solicitation-based protocol and propose an adaptive packet aggregation mechanism for header compression. The proposed mechanism will make use of the solicitation-based MAC protocol and make a tradeoff between delay time and compression efficiency. Tsan-Pin Wang 王讚彬 2011 學位論文 ; thesis 68 zh-TW
