چکیده
In VANETs the trade off between energy efficiency and throughput is one of the main constraints since the medium is time varying wireless channel. In this work we introduce fragmented transmission scheme in to VANETs that improve the energy efficiency pursuing high throughput. In existing systems contention window and back off stage is adapted according to mobility of vehicular node. Along with impact of mobility current channel state also considered in this paper to make the system energy efficient. The simulation results show that the proposed scheme improves throughput making the system energy efficient.
