Ad-hoc network is a dynamic wireless network, composed of mobile nodes without the aid of centralized administration, where nodes have limited transmission range. Security is challenging issue due to the mobility of nodes can lead to dynamic topology, intermediate nodes act as a router can forward packets. Therefore, authentication the source and forwarding packets with cryptographic mechanism and valid MACs is inappropriate because the data with encrypted key can send in same path can be modified by the attacker node. This paper presents a clustering mechanism with multi-hop communication and the source authentication is also done.
