Security is an essential service for wired and wireless network communications. It is very challenging for researchers to provide comprehensive security for wireless networks with the desired quality of service from all possible threats. Providing security becomes even more challenging when the participating nodes are mostly less powerful mobile devices. In this paper, we review different protocols with a particular focus on security aspects. Secure wireless networks have to meet five security requirements: confidentiality, integrity, authentication, non-repudiation and availability. The analyses of the secure versions of the proposed protocols are discussed with respect to the availability and security of routing in wireless network. In the presence of malicious nodes, the networks are vulnerable to various kinds of attacks. In this paper, we examine routing attacks, such as link spoofing and colluding miserly attacks, as well as countermeasures against such attacks in existing MANET protocols. The proposed Scheme will take care to evaluate various security designs and to implement in existing protocols. Efforts will be made to make wireless networks data transfer reliable. Algorithm will be developed to achieve stable data transfer. Finally effort will be made to merge the existing scheme with new scheme to get better scalable design.
