Vehicular Ad hoc NETwork (VANET) is a highly dynamic network. The security and the performance are the key issues of the network. The security enhancement may leads to the performance degradation and vice versa. It is necessary to enhance the security while maintaining the performance. This research modifies the procedure to select the group leader. The protocol named VSA is proposed in this dissertation that modifies the procedure to select the group leader. The proper selection of the group leader is necessary to secure the network. It is due to fact that any local node can transfer data to group leader, doesn't affect the performance of network. But the group leader is used in the communication procedure.
