摘要	Data dissemination over long distances in urban scenarios is the foundation of many VANET applications, but rapid shifting in network topology, unstable quality of wireless communication and channel capacity constraints of VANETs pose many challenges to data dissemination. In response, we propose a connectivity-aware data delivery mechanism on the basis of an improved greedy broadcasting. Moreover, we present an in-network and hierarchical data aggregation mechanism to reduce the transferring of the redundant data which result from multi-source data collecting and multi-path data transmitting. Both mechanisms are intended to improve the qualities of data dissemination in VANETs either by enhancing the adaptability to varying traffic flows or by aggregating data in a hierarchical way. © 2012 IEEE.; Data dissemination over long distances in urban scenarios is the foundation of many VANET applications, but rapid shifting in network topology, unstable quality of wireless communication and channel capacity constraints of VANETs pose many challenges to data dissemination.
