| With the rapid development of wireless communication and relative hardware technology, vehicular communication has aroused more and more attentions. As the particularities of vehicular communication, it was mainly used in the fields of traffic management, pre-warning of accident, distribution of services information, interactive applications (such as Internet access) and etc. This paper mainly focuses on the following aspects:1. This paper proposes Min.-Sending Message information distribution arithmetic about single-lane scenario. This arithmetic make use of the V2V communication, save the sending power of AP effectively, improve the space-time validity of information, deduce the delay-time, and extend the range of information. Author makes use of NS2 simulate these arithmetic, analyses the test results of NS2, concludes the system parameter's affection, and deduces the conditions that system parameters should follow.2. This paper proposes and Min.-Sending Message information arithmetic about multi-lane scenario based on the arithmetic of single-lane scenario. This arithmetic could distribute information in a certain block, and could achieve the performance as single-lane scenario arithmetic. Arithmetic had been verified on NS2 tool,3. What's more, this paper proposes a bran-new solution about interactive-application system. This solution is different from traditional hard-switch: Terminals communicate with more than one receivable-equipment synchronously. Solution brought in the mechanism of Signal Diversity in the process of switch. This solution could improve the quality of link layer connection, deduce the delay time, and satisfied the command of interactive applications, make high mobile communication feasible. This paper mainly focuses on the designation of physical layer, and gives the prove feasibility. The Signals-classification module is realized on matlab 2007. According to the simulation results, conclude the conditions that the system parameters should follow. |
