A Mobile-Ad-Hoc-NETwork (MANET) is a collection of wireless nodes that can be set up dynamically anywhere and anytime without using any pre-existing network infrastructure. Nodes within each other's radio range communicate directly via wireless links, while those that are far apart use other nodes as relays in a multi-hop routing fashion. Traditionally Ad-Hoc routing protocols are typically used to deal with the dynamic nature of these networks, which is mainly due to mobility. These protocols typically suffer from a number of shortcomings, such as high routing overhead and limited scalability.
