Mobile Ad Hoc Networks

Mobile Ad-hoc network is a set of wireless devices called wireless nodes, which dynamically connect and transfer information. Wireless nodes can be personal computers (desktops/laptops) with wireless LAN cards, Personal Digital Assistants (PDA), or other types of wireless or mobile communication devices. In general, a wireless node can be any computing equipment that employs the air as the transmission medium.In MANET, a wireless node can be the source, the destination, or an intermediate node of data transmission. When a wireless node plays the role of an intermediate node, it serves as a router that can receive and forward data packets to its neighbour, which is close to the destination node. Due to the nature of an ad-hoc network, wireless nodes tend to keep moving rather than stay still. Therefore the network topology changes from time to time.The security of MANET becomes increasingly important which needs the serious attention of the research community, as availability, integrity, and privacy are the main concerns of any secure wireless network. Several secure solutions for wireless mobile networks have been proposed by far, but most of them are prevention techniques.
