Secure VANET from vampire attack using LEACH protocol

In modern years we see some growth in technology and for better traffic control on road with these some technologies the moving vehicle can do the better communication in Ad-hoc network which developed a new kind of technology like Vehicular Ad-hoc Network(VANET). VANET provides wireless communication with vehicle to road side unit. VANET can perform the communication between V2V, V2I, I2I. VANET developed an advanced traffic signaling system. To avoid various attack on VANET it provides authentication to every nodes and block the unauthorized nodes. But when nodes are communicate each other on that time for secure data transmission of data clustering is required on that network which is arrange in periodic and dynamic form and selected one cluster head in which they has some features like routing depletion affects the path and resource depletion affects the power, bandwidth and energy consumption which is known as Vampire attack for prevention of this attack use the technique like LEACH protocol(Low Energy Adaptive Clustering Hierarchy). Vampire attack drain the battery power from nodes while transferring data from one node to another.
