Mobile Ad-hoc NETworks (MANET) comprise mobile devices to form an ad hoc network for some ad hoc purpose. So, this special feature of a MANET allows it to be the most demanding technology amongst the users, and the most concerned topic of research in the field of wireless networks. Following the latest trends of research in the field of wireless communication, this paper attempts to focus on some growing issues in MANETs. Security, one of the most important aspects of communication, which faces severe challenges due to various constraints imposed by MANET, is discussed in this paper including vulnerabilities, attacks, various security goals and the applications of MANET.
