Abstract
A method for constructing a virtual grid () for routing data via wireless sensor nodes () of a sensor field (), the method comprising: flooding the sensor field () to identify a first terminator (V), the flooding originating from a first node (V); flooding the sensor field () to identify a second terminator (V), the flooding originating from the first terminator (V); and forming a main communication path () by selecting nodes between the first and second terminators (V, V); wherein the virtual grid () is constructed by flooding the sensor field () such that each node in the sensor field () is assigned a row identifier relative to the main communication path (), the flooding originating from the nodes belonging to the main communication path (); and wherein each node is assigned a column identifier according to its hop count from the first terminator (V).
