A Study on MANET Attacks, Security Concerns

Abstract

Due to the fast changing scenario in field of wireless networking, MANET has emerged as a most promising area of research. MANET is self-organized network of mobile nodes with continuously changing topology. MANET has extensive range of applications like military, rescue operations during natural calamities, commercial sectors, local level network/PAN etc. Due to basic essentilas of being ad hoc, MANET is more prone to attacks. In this paper we will take a brief overview of several routing protocols, Attacks in MANET at different layers, and possible security measures.
