This work provides scalable, threshold authentication scheme in ad hoc networks. We present detailed security threats against ad hoc routing protocols, specifically examining cluster-based routing. Our proposed protocol, called “authentication based on multilayer clustering for ad hoc networks” (AMCAN), designs an end-to-end authentication protocol that relies on mutual trust between nodes in other clusters. The AMCAN strategy takes advantage of a multilayer architecture that is designed for an authentication protocol in a cluster head (CH) using a new concept of control cluster head (CCH) scheme. We propose an authentication protocol that uses certificates containing an asymmetric key and a multilayer architecture so that the CCH is achieved using the threshold scheme, thereby reducing the computational overhead and successfully defeating all identified attacks. We also use a more extensive area, such as a CCH, using an identification protocol to build a highly secure, highly available authentication service, which forms the core of our security framework. Keywords and phrases: authentication, clustering, cluster head, ad hoc network, multilayer.

INTRODUCTION
Mobile ad hoc networks consist of devices that are autonomously self-organized into networks. In ad hoc networks, the devices themselves are the network, and this allows seamless communication, at low cost, with a selforganizing capability, which makes mobile ad hoc networks completely different from any other networking solution.

Mobile ad hoc networking is one of the most innovative and challenging areas of wireless networking. Ad hoc networks are a key step in the evolution of wireless networks. An ad hoc network is a collection of wireless mobile hosts forming a temporary network without the aid of any established infrastructure or centralized administra
