To face the short lifetime of the WSN, the objective is to optimize energy consumption while maintaining the full sensing coverage. A major technique to save the energy is to use a wake-up scheduling protocol through which some nodes stay active whereas the others enter sleep state so as to conserve their energy. This technique presents an original algorithm for node self-scheduling to decide which ones have to switch to the sleep state. The novelty is to take into account the best shortest path among the nodes in wireless sensor network .Hence, the sensed data from the network is transmitted over the best shortest path by verifying the updates in the routing table.
