A Mobile Ad-hoc NETwork (MANET) is a decentralized network of autonomous mobile nodes, able to communicate with each other over wireless links. Due to the mobility of the nodes, the topology of the network changes spontaneously, therefore use of conventional routing tables maintained at fixed points (routers) is not suggested. Such a network may operate in a standalone fashion. There are various routing protocols available for MANETs. The most popular ones are DSR, DSDV and ZRP. The Zone Routing Protocol (ZRP) is a hybrid routing protocol that proactively maintains routes within a local region of the network. ZRP can be configured for a particular network through adjustment of a single parameter, the routing zone radius.
