A Protocol for Mobile Ad Hoc Network
Location-based routing for scalability. Many existing routing protocols proposed within the MANET working group of IETF, are designed to scale in networks of a few hundred nodes. They rely on state concerning all links in the network or links on a route between a source and a destination. This may result in poor scaling properties in larger mobile ad hoc networks or when nodes frequently disconnect to save battery. More recently, there has been a growing focus on a class of routing algorithms that rely largely, or completely, on location (and possibly mobility) information. These algorithms improve network scalability by reducing the total routing overhead.
