Dynamic spectrum management using frequency selection at licensed and unlicensed bands for efficient vehicle-to-vehicle communication

Background: The exponential increase in pattern of vehicles on the roads demands a need to develop vehicular infrastructure that may not only ease congestions and provide better experience but also pivot levels safety among users. The development wireless technology has made it convenient for machines, devices interact with one another. efficacy this communications relies utilising current available enable information be shared efficiently. In wake advancement technology, new dynamic spectrum management (DSM) vehicle-to-vehicle (V2V) communication coexists existing Long-Term Evolution (LTE) network throughput V2V is proposed. This will some solutions more efficient infrastructure. Methods: This paper focuses utilization DSM by selecting an appropriate frequency band through selection licensed unlicensed bands vehicles. Further investigations are done identify effect interference observing path loss, SINR, various interfering users. Results: results show performance proposed augments significant improvement overall signal-to-interference-plus-noise ratio (SINR) value reduced up 60% when compared fixed allocation. Conclusions: Although still affected from cellular users, remains sufficient transmit other vehicles.
