A Reliable Research to Preserve Security in Infrastructure less Networks: MANET

Abstract

Mobile ad hoc networks (MANETs) are a unique wireless network which does not relay on any defined infrastructure. Compared to wired networks, MANETs can be attacked easily due to absentness of centralized monitoring authority. The nodes in these networks are dynamic and they set the path to transfer data. Due to this nature of MANET there is a need to incorporate routing protocol with security mechanism. The available cryptographic algorithms supports authentication to escape from passive and active attacks. Here this problem is addressed using Intrusion detection mechanism (IDM) and Position-based Opportunistic Routing protocol (PORP) in a reliable and timely manner.
