Mobile Ad-hoc NETworks (MANETs) are autonomously self-organized networks without infrastructure support. To provide communication within the network a routing protocol is used to discover routes between nodes. The main aim of the routing protocol is to have an efficient route establishment between a pair of nodes, so that messages can be delivered in a timely manner. Routing in the MANETs is a challenging task which has led to development of many different routing protocols for MANETs.
