1. 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, the flooding originating from a first node;

    flooding the sensor field to identify a second terminator, the flooding originating from the first terminator; and

    forming a main communication path by selecting nodes between the first and second terminators;

    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.
