A hybrid of node degree and k-shell index is more effective at identifying influential spreaders and has less computational overhead than either of these traditional measures.

In the overall effort of reducing CO2 emissions especially in large cities vehicular communications can play an important role. Intelligent transportation systems, which aim to use information and communication technology are considered to be a major factor in this effort. Eco-routing is already used to suggest most environmental-friendly routes in order to reduce overall mileage and CO2 emissions based on historical data. In this paper we propose a real time system based on Dedicated short-range communication (DSRC) capabilities in order to reroute vehicles to the most ecological route, avoiding congested roads and minimizing the overall travel time and C02 emissions. © 2013 IEEE
