NOAH ("No Adhoc routing agent" ) doesn't send any routing related packets , it only supports direct communication between wireless nodes and mobile nodes in case mobile IP is used
NOHA supports single hop communication in mobile IP (i.e., between wireless nodes or between base stations and mobile nodes). It does not send any routing packets towards intermediate nodes since it is used when multi-hop wireless routing is undesired. See the following link: http://icapeople.epfl.ch/widmer/uwb/ns-2/noah/
it supports only direct communication between wireless nodes . Routes manually entered into the table by a network administrator or by loading a pre -defined configuration file . In case of failure or down connection, route must be reconfigured manually to overcome any loss in connectivity
