Abstract: A mobile ad hoc network (MANET) is a wireless network without the support of any fixed infrastructure. Security is one of the main challenges in ad hoc network due to dynamic topology and mobility of nodes.Organizing mobile nodes into manageable clusters can limit the amount of secure routing information. Under a cluster structure, mobile nodes are managed by nodes called cluster heads. The clusterhead role is resource consuming since it’s always switched on and is responsible for the long-range transmission, for example to send a bit over 10 or 100 m distance, Manet’s nodes consume resources that can perform thousands to millions of arithmetic operations. In this work, we present a clustering algorithm based on node trust and performances called (CATP) , where the clusters are formed around the trustworthy , the densest and the most powerful nodes.
