    Abstract: 車載隨意行動網路(英語:Vehicular Ad-Hoc Networks,縮寫為VANETs),又稱車用行動通訊網路。這種網路是一種行動通訊技術,是以移動中的車輛及交通設施為節點,利用無線通訊技術,來形成行動網路。加入這種網路的車輛,會成為一個無線節點,或是無線路由。
    ;Vehicular Ad Hoc Network (VANET) is an emerging area of wireless ad hoc networks that facilitates ubiquitous connectivity between smart vehicles through Vehicle-to-Vehicle (V2V) or Vehicle-to-Roadside (V2R) communications. Vehicles located inside the VANETs are communication nodes, relay nodes or routers.
    How to design novel communication protocols to support various applications have been an important research challenge in vehicular networks. In particular, energy shortage and energy crisis are increasing severe problems that hinder economy developments in the world. Many automotive manufacturers have conduct researches on enhancement of interior of vehicles with green technologies, for instance hybrid technology of gasoline and electric engine, or full electric vehicles. Thus, developing energy efficient communication protocols in VANETs is imminent. This dissertation is to study aforementioned important research issues and proposes energy-efficient and traffic density awareness routing protocols for VANETs. An energy efficient geocast routing protocol is also proposed to save the energy in routing packets to region of interests. Extensive simulations are conducted to evaluate performances or proposed two routing protocols. Simulation results show that proposed protocols outperform compared routing protocols in literature in terms of network performance and green performance. Moreover, traffic density prediction model, inter-vehicle connectivity model and energy efficiency on packet forwarding are studied. As a result, this dissertation presents a link-stability based routing protocol for dense vehicle density vehicular networks and a min-delay based routing protocol for sparse vehicle density network environment, respectively.
