Arranging mobile sensors into a predetermined pattern

摘要

Moving a target mobile node (10;52a) to arrange a number of mobile nodes (10;52) includes determining a first direction. A first relative position for each of the neighbouring mobile nodes (10;52b) of the target mobile node (10;52a) is established. The target mobile node (10;52a) moves according to a first alignment procedure to align the mobile nodes (10;52) in the first direction. A second direction substantially orthogonal to the first direction is determined. A second relative position for each of the neighbouring mobile nodes (10;52b) is established. The target mobile node (10;52a) moves according to a second alignment procedure to align the mobile nodes (10;52) in the second direction.
