design and evaluation of two scalable protocols for location management of mobile nodes in location based routing protocols in mobile ad hoc networks

heretofore several position-based routing protocols have been developed for mobile ad hoc networks. many of these protocols assume that a location service is available which provides location information on the nodes in the network.our solutions decrease location update without loss of query success rate or throughput and even increase those.simulation results show that our methods are effective and the algorithms are distributed and can keep scalability in scenario of increasing nodes density.
