1. A forwarding method for data broadcast reduction in a Vehicle Named Data Networking (VNDN), the method comprising:
(a) setting name centrality (NameCent) count data with respect to an interest packet received by a node of the VNDN;
(b) measuring, by a Received Signal Strength Indicator (RSSI), a power level of signal received from an access point (AP) or any other vehicle in wireless communication;
(c) calculating a weight of the interest packet for a data forwarder in a current node or a previous node based on the name centrality (NameCent) count data and signal strength measured by the Received Signal Strength Indicator (RSSI); and
(d) determining a potential forwarder of a data packet by comparison of variables of the weight calculated in step (c),
wherein, in step (c), each weight is calculated with logic of the following equation:
