From: Determining Localized Tree Construction Schemes Based on Sensor Network Lifetime
The indoor deployment location of nodes and four data-gathering topology maps with localized tree construction schemes using the PRR data obtained by UCLA/CENS group: (a) the lowest ETX parent selection, (b) the random parent selection scheme (all possible links) with MHR, (c) the lowest ETX parent selection scheme with MHR, and (d) the balanced parent selection scheme with MHR.
