Smooth hilbert space filling curve for minimizing traversal complexity in covering a monitoring area
Maznah Bte Kamat · 2008
Mobility strategies for a sink node in WSNs serve to move the sink in traversing a monitoring area to collect data from the sensor field and reduce communication relay and thus maximize network lifetime. For periodic data collection, in-order traversal is required. This paper discusses the various in-order mobility strategies in covering an area of interest. Simulation result shows that linear Hilbert space-filling curve produces high percentage of switching direction which adds on to traversal complexity. This complexity is eliminated using curvature path called Smooth-Hilbert.
