A Study on MANET and its Security Concepts

The Computer Network technology is developing rapidly and the recent advances have introduced a new technology for wireless communication over the internet in future in MANET. It becomes the popular research topic in recent years. Security has become one of the most important challenges against malicious behaviours and nodes in MANET and there are more studies focused on several security problems. After quantifying and analysing the network information Security elements like integrity, availability and confidentiality, we are going to discuss about the overview of security issues in detail with respect to services, parameters, applications, attacks and challenges, some of the applications that is used in MANET and also the various types of attacks that can be involved internally as well as externally such as delay of packets, time consumption and bandwidth etc.
