Uma solução para disputa por largura de banda em aplicações deentretenimento para redes veiculares

Abstract

The vehicular networks were designed to provide the possibility of communication among vehicles. By means of this communication, the vehicles become able to get and share assistance contents to the drivers, traffic safety and entertainement. In order to provide these sort of contents, applications aiming at becoming more pleasant and safe the time consumed are created. The applications with the specific function of entertainement carry out their functions by means of the distribution of contents such as songs, videos, web pages, and they have great importance and usefulness since they act in an increasinglychaotic environment, implied by problems caused by the own vehicle traffic. One of the greatest challenges regarding to the entertainement applications is the high demand for the bandwidth. In some situations, this resource is not enough to meet all the demands from the users at the request time. By the time the content requests are not entirelymet, interest conflicts take place in the competition for resources, decreasing the users satisfaction. For these applications, which are of collective use, to make available their resources with all their benefits, is essential to the data use of the user and environment context. This study uses a solution, available in literature, to these conflicts, taking intoconsideration the most appropriate algorithm to the environment and application context, by means of (CReMe - Conflict Resolution Methodology). The results have shown that it was possible use the methodology to solve the conflicts, in an adaptively way to thecontext, balacing the resources consumption and the user satisfaction.
