All-to-all Broadcast for Vehicular Networks Based on Coded Slotted ALOHA

Abstract:

Coded slotted ALOHA (CSA) is an uncoordinated multiple access technique that promises throughputs close to those of coordinated multiple access methods. It was originally proposed for unicast transmission in satellite networks. The main idea is to exploit successive interference cancellation which, under certain assumptions, makes CSA very similar to codes on graphs. In this talk, I will describe how CSA can be used for all-to-all broadcast in vehicular networks. We will compare CSA with the carrier sense multiple access currently adopted for vehicular communications. We will discuss how the theory of codes on graphs helps to design good CSA schemes and how the design criteria need to be adapted to vehicular communications.
