Mobile Ad-hoc NETworks (MANETs) comprises of a set of nodes connected by wireless links. The network is ad hoc because it does not rely on a preexisting infrastructure, such as routers in wired networks. Routing in MANETs is a challenging task due to dynamic topology and error prone shared environment. Data is sent between nodes in a MANET by hopping through intermediate nodes, which must make decisions about where and how to route the data. MANET faces several problems because of node mobility, network traffic, network size, and the possibility of node faults. The efficiency and behavior of a MANET depends on how well information can be passed around and delivered.
