Existing move-restricted node self-deployment algorithms are based on a fixed node communication radius, evaluate the performance KIDS FOOTWEAR based on network coverage or the connectivity rate and do not consider the number of nodes near the sink node and the energy consumption distribution of the network topology, thereby degrading network relia

KIDS FOOTWEAR During a routine analysis of whistlers on the wide-band VLF recording of the DEMETER satellite, a specific signal structure of numerous fractional-hop whistlers, termed the "Spiky Whistler" (SpW) was identified.These signals appear to be composed of a conventional whistler combined by the compound mode-patterns of guided wave propagat
