Abstract
The present invention relates to a method for routing at least a data packet in a wireless sensor network (10), the wireless sensor network (10) comprising: at least a source node (S) that is configurable to transmit at least a data packet; at least a destination node (D) that is configurable to receive the data packet transmitted by the source node (S), and interconnectable network nodes (si) between the source node (S) and the destination node (D) that are configurable to receive and forward the data packet, the method comprising the steps of: operating the network nodes (si) according to a sleep-active schedule comprising at least a sleep mode and an active mode, and configuring the network nodes (si) to have information on their own geographic location and the geographic location of the destination node (D), the method further comprising the steps of: dividing the wireless sensor network (10) into a plurality of disjoint areas (A0, AM-1, A1, A2) that are separated by boundaries; separating each area (A0, AM-1, A1, A2) into at en least two regions, the regions being an inner boundary region (I), a central region (C) and an outer boundary region (O); selecting forwarding nodes ou…
