Abstract:
|
In ad-hoc networks, autonomous nodes collaborate to route information
through the network. Commonly, nodes are end-systems and routers at
the same time. In case nodes have a notion of their geographic
position, a position-based routing protocol can be used, whose
properties of statelessness and fast adaptability to changes in the
topology match very well with the characteristics of ad-hoc networks.
Position-based routing does not require the maintenance of routes but
forwarding decisions are made locally, based only on the node's own
position, the positions of its neighbors and the position of the
destination. The routing algorithm is complemented by a location
service through which a node can obtain the position of a packet's
destination.
We will introduce components of position-based routing, discuss some
of the previously published routing algorithms, and present an
application scenario where position-based routing can be used for
inter-vehicle communication.
