A Survey on Various Enhancements Made on ZRP

MANET is a self organizing and self configurable infrastructure less network of mobile nodes connected by wireless where the nodes move arbitrarily. Routing is a critical issue in Mobile Ad Hoc Networks. One of well-known protocol for Ad hoc networks is Zone Routing Protocol. However, many useless control packets are used resulting in the increase of network load and decrease of network performance. This paper studies various enhancements that have been made on ZRP to improve its performance
