MANET:Vulnerabilities and Applications

A mobile ad hoc network is an autonomous collection of mobile devices (laptops, smart phones, sensors, etc.) that communicate with each other over wireless links and cooperate in a distributed manner in order to provide the necessary network functionality in the absence of a fixed infrastructure. This type of network, operating as a standalone network or with one or multiple points of attachment to cellular networks or the Internet, paves the way for numerous new and exciting application. Application scenarios include, but are not limited to: emergency and rescue operations, conference or campus settings, car networks, personal networking, etc. In this era of wireless devices, Mobile Ad-hoc Network (MANET) has become an indivisible part for communication for mobile devices. A MANET is a collection of wireless nodes that can dynamically form a network to exchange information without using any preexisting fixed network infra structure. The special features of MANET bring this technology great opportunity together with severe challenges. Mobile ad-hoc network (MANET) is one of the most promising fields for research and development of wireless network. As the popularity of mobile device and wireless networks significantly increased over the past years, wireless ad-hoc networks has now become one of the most vibrant and active field of communication and networks. Due to severe challenges, the special features of MANET bring this technology great opportunistic together. This paper describes the concept, features, status, and applications of MANET. Also include the several challenging issues, emerging application and the future trends of MANET.
