An energy efficient multi hop sensor network cannot avoid the energy hole problem, which is the rapid decrease in the energy of nodes around the sink. Also as a sensor network has a limited node resources and unexpected changes of external environment, its nodes should show energy efficiency, reliable data transmission, and topological adaptation to the(More)
The traditional cluster routing method is a typical method for enhancing an energy efficiency, which selects cluster head in order to send the aggregated data arriving from the nodes in cluster to a base station. However the major challenges are the equal distribution of each cluster over the whole sensor network and the energy dissipation caused by the(More)
Mechanically adaptive electronic skins (e-skins) emulate tactition and thermoception by cutaneous mechanoreceptors and thermoreceptors in human skin, respectively. When exposed to multiple stimuli including mechanical and thermal stimuli, discerning and quantifying precise sensing signals from sensors embedded in e-skins are critical. In addition, different(More)
As a sensor network has a limited node resources and unexpected changes of external environment, its nodes should show energy efficiency, reliable data transmission, and topological adaptation to the change of external environment. However, it is not easy to satisfy these requirements at the same time. This study proposes Robust and Energy efficient Dynamic(More)
