Conclusions and Future Work
,For
all network topologies, CCA-Map can achieve good localization results
(below 10%r) for low connectivity levels when using ranging
,Using
connectivity only, CCA-Map achieves 20%r or better for reasonably
low connectivity levels
,CCA-Map
almost always significantly better than MDS-Map
,CCA-Map
does not require many anchor nodes
,Future
Work
–Study
irregular and anisotropic networks in more detail (Milcom paper)
–Improve
stability of MDS and CCA in range-free case
–Implement
algorithm in testbed to study computational complexity
,May
exploit hierarchical nature of testbed to run localization on only
clusterheads
