Mobile Ad hoc NETwork (MANET) comprises of nodes, which are free to move randomly, yet cooperate to forward packets between source and destination over a multi-hop wireless network. Due to absence of any fixed node, each node acts as a router, providing routing capability for the MANET. Various protocols for discovery of routes between any two MANET nodes have been designed. These protocols are divided into two categories as on-demand protocols and table driven protocols. Dynamic Source Routing (DSR) and Ad-hoc On-Demand Distance Vector (AODV) are the two most matured on-demand routing protocols, while Optimized Link State Routing Protocol (OLSR) is most matured table driven routing protocol.
