Abstract— CEAACK MANETs are vulnerable to attacks and this can be reduced by employing a cluster mechanism which ensures that packet transmission occurs without unnecessary delay. Clustering can be made effective in CEAACK MANETs by opting for a cluster head mechanism which ensures that control rests with a single powerful node within a cluster. This cluster head takes on the responsibility of routing the packets efficiently by coordinating with the base station.Cluster heads are also prone to malicious
