In a Mobile Ad hoc NETwork (MANET), mobile nodes move around arbitrarily, nodes may join and leave at any time and the resulting topology is constantly changing. Routing in a MANET is challenging because of the dynamic topology and the lack of an existing fixed infrastructure. The DYnamic MANET On-demand (DYMO) protocol builds on existing Ad-hoc On-demand Distance Vector (AODV) routing protocol, evaluated in the context of sensor networks proposed for MANETs. AODV work only when a data is delivered to them so as to maintain the route to the destination (reactive routing protocol).
