Security attacks and detection schemes in MANET

A Mobile adhoc network (MANET) is considered a collection of wireless mobile nodes that are capable of communicating with each other without the use of a network infrastructure. MANET is particularly vulnerable due to its fundamental characteristics, such as open peer-to-peer architecture, shared wireless medium, stringent resource constraints, highly dynamic network topology and nodes openness to physical capture. Security is most important service for all kind of network communications. MANET should provide security that increases people´s confidence on MANET. In this paper a survey on MANET attacks and detection schemes are presented. This helps to understand different types of attacks and detection schemes required to avoid those attacks.
