Vehicular Ad-hoc Network (VANET) is an emerging technology which allows vehicles on the roads to communicate and exchange information with each other. Broadcast in VANET has gained a lot of attention because it is used extensively in many VANET applications. Recently, Cell Broadcast for streets (CB-S) [1], a cell based algorithm has been proposed and compared favorably to different class of broadcast in VANET. This paper proposes an enhanced version of CB-S called ECB-S which addresses CB-S limitations in selecting rebroadcast nodes only within any other cell and enhance it to include also any node reachable within the transmission range. Simulation study shows that ECB-S outperforms considerably the original CB-S in terms of end-to-end delay under different traffic, density, and mobility conditions.
