Survey of Secure Communication Techniques in Mobile Ad-hoc Network
A Mobile Ad-hoc NETwork (MANET) is an autonomous network comprised of free roaming nodes which communicate wireless by radio transmission. One of the main challenges in MANETs is the design of efficient and light-weight security algorithms that can be handled by devices with limited computational capabilities. Efficiency, reliability and security are (competing) design goals for algorithms suitable for MANETs. Many protocols neglect at least one of these goals: while cryptographic algorithms are typically provable secure and reliable to the extent that lost messages are simply handled with retrials, they marginally consider communication costs.
