An ad hoc network is a multi-hop wireless communication network that supports mobile users without existing infrastructure. In mobile ad hoc networks, security is essential to provide secure communication between mobile nodes by establishing robust and unobstructed routes. There are various secure routing protocols such as SEAD, SAODV, SRP, and three security pillars, namely confidentiality obligations and availability are guaranteed. Authenticated routing for ad hoc networks (ARAN) bridges voids caused by disadvantages of other protocols by providing that authentication, integrity, and non-repudiation gives confidentiality. From the above given protocols it is quite difficult to determine the performance of individual protocol in different network scenario. Therefore, this paper provides an overview of existing routing protocols and based on their review a new method has proposed. The proposed method focuses on the parameters which were not mentioned or considered in the existing protocols. Furthermore, this study will suggest the results which can be expected in future through proposed work.
