Location-centric Networking in Distributed Sensor Networks

Emerging sensor network technology interconnects spatially distributed sensing devices deployed to monitor and interact with the surrounding physical world [?], [?], [?]. Each device (node) in the network senses a limited neighborhood using one or more of its modalities. A single node, however, cannot often sufficiently characterize the physical world due to its limited sensing capability and reliability. Therefore, collaboration among a set of nodes is necessary to produce a complete picture of the area.
