Theoretical Analysis of Spread-Spectrum Push/Pull Type Packet Compensation Protocol on Local Broadcasting Services

The purpose of this paper is to compensate loss packet in the broadcasting system using road to vehicle communications (RVC). Authors have proposed and evaluated the push-type and pull-type packet compensation protocol. These protocols are the loss packet compensation protocol using inter-vehicle communications (IVC). In this paper, the push/pull-type packet compensation protocol with common spreading sequences for broadcasting system is proposed. The average packet acquisition time is analyzed. By comparing with the pull-type packet compensation protocol, the push/pull-type packet compensation protocol is more efficient than the pull-type packet compensation protocol.
