Paper Abstract
Multihop wireless networks are ideal as infrastructures for
location-aware network applications, particularly for disaster recovery
operations. However, one missing component is an efficient and scalable
distributed data location service. Existing approaches impose
significant communication overhead on the underlying wireless layer and
generally limit the total number of locatable objects in a network. To
address this problem, we present the Integrated Data Location Protocol
(IDLP), which provides scalable location of a large number of objects by
integrating compressed summaries of object signatures into the routing
layer. We evaluate our approach using extensive simulations in Qualnet,
as well as detailed measurements from a deployed AODV-implementation on
the UCSB MeshNet testbed. Results show that IDLP maintains low
communication overhead while efficiently locating up to a hundred
objects per node.
