A Mobile Ad hoc NETwork (MANET) is a network of mobile devices that communicates through wireless links without the use of any fixed infrastructure or centralized control. A wireless technology has opened the doors for new emerging applications of networking and one of the emerging and potential areas is the domain of Mobile Ad hoc NETworks (MANETs). MANET is a collection of wireless mobile nodes without the need for centralized access points. In order to achieve better security for the network, secure routing has been used to protect the routing protocol against malicious attaches in MANET. In this paper, a detailed study of IEEE 802.11 access mechanism and its vulnerabilities are given.
