Routing plays an important role in providing better services to the users in UVANET. In this paper, a novel routing protocol is proposed for UVANET to support non-safety applications. We consider a non-safety application wherein the drivers and passengers of different parking lots can play multiplayer games with each other. To play the games smoothly, the game data should reach the destination in a minimum time. Simulation results show that when the vehicle density in the city area is high, the proposed protocol meets the end-to-end delay tolerance of 100 ms. Finally, an experiment is performed to validate the proposed routing protocol by running a simple puzzle game in a UVANET prototype designed in an indoor laboratory environment and in an outdoor environment.展开更多

Political participation has to be affected by the social and economic development, political system, social and environmental factors, countries generally believe that collaboration between the Government and social organizations, networks of enterprises, schools and other interested parties are currently the main mode of network governance. College students are the main power of the network of political participation, the university plays an important role in the political participation process. Therefore, this article takes online political participation of college students as a starting point, through questionnaires and case interviews and other methods to investigate the current status of college students online political participation, analyze network characteristics and problems of college students in political participation, to guide the college network path which provides reference for orderly participation in political studies.展开更多
