This paper is aimed to detect the malicious behavior of the nodes by first selecting some set of leader nodes. The leader nodes are those set of nodes in a network which monitor the whole network of nodes. The set of leader nodes is referred as the dominating set. A set is dominating if all the nodes of the network are either in the set or neighbors of nodes in the set. The efficiency of a commanding-set-based broadcasting or routing is mainly dependent on the overhead in constructing the dominating set and the size of the dominating set. The leader nodes are working in the promiscuous mode and they overhear traffic in its neighborhood. In promiscuous mode the system (NS-2) by-pass the MAC(Media Access Control) filtering procedure and the nodes working in promiscuous mode, receives the packets that are sent or received by any other node in its transmission range even if the packets were not intended for that node, this phenomenon is commonly known as packet overhearing. The leader nodes also monitor the topology of the network and reports if there are any changes in the network on the basis of a certain criteria, moreover they also detect if any packet is modified, and the snooping attack and calculate the forward packet ratio.
