With the emergence of mobile ad hoc networks it is now possible to access network accessing and communicate data in an area where no fixed infrastructure exists or existing infrastructure is not available. Since in ad hoc networks, the exact copies of the same content are stored at various locations. Therefore in order to prevent from various attacks based on the content; it becomes important to have some security solutions. In this paper, we propose an efficient content authentication method in ad hoc network. Foremost, the challenges in ad hoc networks have been mentioned in this paper. This paper focuses on secure packet forwarding in ad hoc networks and proposes a new solution based on observation by all the neighboring nodes to mitigate the effects of adverse situations caused by malicious nodes. This prevention mechanism exploits all well-behaving nodes' local knowledge to by pass misbehavin g nodes, evaluate path quality and choose the most reliable path for data forwarding. In this paper, a new solution for mobile ad hoc networks based on observation by all the neighboring nodes is presented.
