Abstract: Mobility of nodes in ad hoc networks results in route loss, poor longevity of established routes, asymmetric communications links, increases the control traffic overhead and affects the performance of the routing protocol. However, mobility can be exploited to improve route longevity. In situations where the information used for routing is absent, the routing protocols that depend upon this information will fail to operate correctly. This paper studies three schemes that make use of alternative |self-dependent| information, the Heading Direction Angle, to provide a mechanism for establishing and maintaining robust and long-lived routes.

Keywords: ad hoc networks; heading direction; link stability; node mobility; protocols; routing protocols; podcasting; social networking; Web 2.0; link longevity; mobile communications; route longevity.
