A Mobile Ad-hoc NETwork (MANET) is a self-configuring infrastructure less network of mobile devices connected by wireless. These are a kind of wireless Ad hoc Networks that usually has a routable networking environment on top of a Link Layer Ad hoc Network. The routing approach in MANET includes mainly three categories viz., Reactive Protocols, Proactive Protocols and Hybrid Protocols. These traditional routing schemes are not pertinent to the so called Intermittently Connected Mobile Ad-hoc NETwork (ICMANET). ICMANET is a form of Delay Tolerant Network, where there never exists a complete end - to - end path between two nodes wishing to communicate.
