Security in Mobile Ad hoc Networks: Challenges and Solutions

Ad hoc networks are a wireless networking paradigm for mobile hosts. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure. Instead, these networks are selfconfigurable and autonomous systems which are able to support movability and organize themselves arbitrarily. These unique characteristics of ad hoc networks pose a number of challenges for the implementation of security infrastructure in the wireless network system design. In this paper, we study the ad-hoc architecture thus understanding the vulnerabilities and security goals. Further, we discuss the various security attacks and explore approaches to secure the communication.
