Abstract : Vehicular Ad-hoc Networks (VANETs) are given more research importance in the recent days, because of its special characteristics. The VANETs are different from MANETs (Mobile Ad-hoc networks) in features like frequent high vehicle mobility, frequent link failure, and frequent topology changes. However, there are also few other hitches which affect the efficiency of such networks. Instability is the major problem that has to be taken care. In this paper, we are introducing an algorithm to enhance the system with a security feature being integrated with the existing overhead reduction algorithm. This is an enhanced algorithm that has been designed over the existing Overhead Reduction Algorithms. The main aim here is to secure the network and also to measure the sub-optimal numbers of the overhead messages transferred between the cluster head and the cluster members. In the first part we reduce the overhead messaging by limiting few of the parameters and in the next step we do introduce a law executer into the network which acts as a secured authenticator for the nodes to enter the Network. NS2 simulator has been used to evaluate the performance of the mentioned algorithm.
