A Survey of Adaptive Gateway Discovery Mechanisms in Heterogeneous Networks

Abstract

The communication range of devices within a mobile ad hoc network is inherently restricted. One way of enhancing the communication range of a mobile ad hoc network, is to interconnect it to a wired network like the internet, thus forming a heterogeneous wired cum wireless network. This interconnection also enables mobile nodes to access internet services, and is achieved through gateways. Mobile nodes in the ad hoc network need to discover and register with a gateway in order to obtain Internet connectivity.
