A major challenge faced in Mobile Ad Hoc NETworks (MANET) is locating devices for communication, especially with high node mobility and sparse node density. Present solutions provided by ad hoc routing protocols range from flooding the entire network with route requests, to deploying a separate location management scheme to maintain a device location database. In this paper, the authors propose a novel scheme called Acquaintance Based Soft Location Management (ABSLM) in MANET. In ABSLM, nodes make use of the real life concept of making acquaintances and keeping in touch with them regarding each other's current locations.
