A Scheme for Expanding Grid Size of Geographical Adaptive Fidelity
Tokuya Inagaki, Susumu Ishihara · 2007
We propose novel power saving techniques hierarchical GAF (HGAF) and enhanced HGAF (EHGAF). They use layered with GAF (geographical adaptive fidelity) which uses location information of each node in a wireless sensor networks (WSNs) for grouping of nodes.
