Abstract: Mobile ad hoc Network is a self- configuring infrastructure-less network of nodes connected through wireless link. Each node in the network can act as router as well as host to find paths to exchange information. For finding paths, location based routing protocols have been developed for mobile ad hoc networks. This paper presents performance analysis of location based routing protocols, Greedy Perimeter Stateless Routing (GPSR) and Zone Routing Protocol (ZRP), based on metrics such as throughput, end-to-end delay, packet delivery fraction, and routing overhead.
