Analysis of Privacy Preservation on Mobile Ad-Hoc Networks

Mobile Ad-hoc Network (MANET) privacy protection is more complex than wired networks. Providing privacy protection for MANET with a low bandwidth connection and low-powered mobile nodes is the most challenging. In this analysis, privacy-preservation routing algorithms are studied to highlight the security issues and available techniques. In MANET, traditional anonymous routing algorithms are primarily based on anonymity and unlikability. As per the study, most methods rely on cryptography algorithms like public key cryptosystems and symmetric keys to achieve privacy preservation objectives. Studying the content protection with respect to unobservability as well as unlikability of mobile nodes. Traditional techniques to identify malicious nodes through the routing packets information having some limitations, which will be used to initiate many active and passive attacks in MANET. This study mentioned different existing techniques such as location-based authentication, trust mechanism, cryptography algorithm to preserve privacy in MANET.
