Ad hoc networks allow wireless devices to form a network without any pre-existing knowledge of
configuration or topology. Large-scale networks consist of hundreds or more nodes and are unable to use
traditional broadcast routing algorithms due to lack of scalability. Geographic algorithms use nodes'
geographical locations to route traffic without topology knowledge, but still require knowledge of the
destination node's location. This location is often provided up by location service protocols although many
of these too use broadcast schemes which limit their scalability. This work describes a location server that
uses self-organising behaviour that is often seen in nature to minimise transmission overhead and maximize
scalability. The approach outperforms existing solutions by significant margins.
