Abstract:
The present invention relates to a system and method for managing the sleeping mode of wireless sensor nodes (110) in a wireless sensor network for managing sleeping schedule of the wireless sensor nodes (110) during an event or crisis. The wireless sensor network comprises of at least one gateway and a plurality of wireless sensor node (110), wherein each wireless sensor node (100) includes a critical stage management module (111) and sleeping schedule management module (112) for managing sleeping mode during an event or crisis.
Abstract:
A method for secure direct communication between a communicator and a sensor node is disclosed. The method (100) comprises sending a request packet from the communicator to the sensor node (102), processing the request packet in the sensor node (104), sending a corresponding data packet from the sensor node to the communicator (106) and processing the corresponding data packet in the communicator (108).
