Abstract:
1. A method for assigning addresses to nodes in a wireless network, comprising: defining an address space as an n-dimensional grid, each grid intersection having coordinates of a corresponding possible node of a wireless network, a number of components of each coordinate being equal to a dimensionality of the grid, and the coordinates forming a logical address of the corresponding possible node; selecting a component of the coordinates to be associated with a predetermined value; assigning, by a parent node to a child node joining the wireless network, an unallocated logical address as a child node address such that any component of the child node address is modified, by one, from a corresponding component of the parent node if the selected component of the parent node has the predetermined value; and otherwise assigning, by the parent node to the child node joining the wireless network, an unallocated logical address as a child node address such that the selected component of the child node address is modified, by one, from the selected component of the parent node.
