Adaptive Multicasting Using Common Spreading Codes in Infrastructure-to-Vehicle Communication Networks

This paper presents a novel code allocation scheme for multicasting in infrastructure-to-vehicle CDMA-based wireless networks. In a CDMA-based cellular network, to maximize the utilization of bandwidth and to minimize the overhead under varying channel conditions, the proposed scheme discusses how cellular and vehicular networks can collaborate in multicasting. Multiplexing is achieved by assigning a common variable rate Orthogonal Variable Spreading Factor (OVSF) code to all members of a multicast group.
