Structure-free message aggregation and routing in traffic information system (SMART).

In a VANET (Vehicular Ad-Hoc Network) environment, it is highly probable that multiple nodes detect and report common events. Hence, elimination of redundant messages can help in efficient bandwidth usage. Data aggregation has also been identified as another potential tool to address broadcast storm in VANETs. Though many aggregation and in-network filtering schemes have been proposed, few studies have been done to combine the two approaches in a structured fashion in order to reap the full benefits.
