Abstract
This is a weighted cluster algorithm based on re-clustering approach for OLSR and DSR protocols in MANET. In this protocol, all the nodes of the networks are clustered into a single cluster; we have analyzed the way how to compute the trusting values according to their interaction performances between the nodes. Based on the trusting value, we can decide and check whether the connection between the two nodes is reliable or not. On the basis of no. of reliable connections, we can choose the cluster head in the cluster, and the nodes which hold solid association with cluster head will be the base nodes, base nodes and the cluster head can work together for being the service providing congregation (group) for the cluster. Each member will circulate a secret share mechanism which will be a part of secret key for itself, and come into being the parameter of authentication in the processing of investigation about the up to date requirement in the next cluster, and the obscure and secret share mechanism can also be authenticated by the node itself. One node has been confirmed as a malicious node at a time; cluster head broadcasts the information to all the cluster members and refuse to provide updating service for the particular malicious node. The protocol has absolute forward confidentiality and backward confidentiality. The keys of nodes and cluster are generated after discussion among the service group members, Man-in-the-middle attack can be resisted by this way. At the same time, the cluster can achieve the periodic update, the cluster head will be reelected, service group will be reformed, subsequently, the key of cluster and nodes will be updated as well.
