Vehicular Swarm Network (VSN) technology enables real time inter-vehicular communications for broadcasting all kinds of data collection, including emergency video with high data rate. A challenge in VSN broadcasting is to achieve a high throughput rate while at the same time assure the delivery of video packet flows to all the vehicles traveling over a highway segment from the accident vehicle. This paper analyzed the throughput- distance relationship model of 802.11p standard in multi-relay VSN with Vehicle Backbone Sub-Network (VBSN). Also, this paper proposed Enhanced Throughput Capacity (ETC) scheme; using GPS, vehicles that positioned close to those throughput-optimal positions are elected as VSBN relays. The aim of this paper is two-fold: a. We analyze the property of optimal position for enhancing the broadcast throughput. b. We demonstrate the performance offered by this ETC scheme; it excludes additional VBSN rebuilt process, and has robustness of high throughput in different traffic density and vehicle speed.
