Abstract:
THE PRESENT INVENTION RELATES TO A METHOD FOR RE-CONNECTING AN ISOLATED NODE IN A WIRELESS MESH NETWORK. WHEN A NODE IS ISOLATED FROM ITS NETWORK, THE METHOD ALLOWS THE NODE TO RE-CONNECT TO ITS NETWORK BY ROUTING THE ISOLATED NODE THROUGH A NEIGHBOURING WIRELESS MESH NETWORK. EACH NETWORK COMPRISES OF A GATEWAY (50) AND A PLURALITY OF WIRELESS NODES. THE GATEWAY (50) INCLUDES A MEMORY (51), AND A PROCESSOR (52) HAVING A COLLABORATION MODULE (53) AND A TRUST MODULE (54). THE COLLABORATION MODULE (53) IS USED TO ALLOW COLLABORATION BETWEEN THE WIRELESS MESH NETWORK AND THE NEIGHBOURING NETWORK. THE TRUST MODULE (54) IS USED TO DETERMINE WHETHER THE ISOLATED NODE BELONGS TO THE WIRELESS MESH NETWORK. EACH WIRELESS NODE (10) INCLUDES A MEMORY (11), AND A PROCESSOR (12) HAVING A COLLABORATION MODULE (13) TO ALLOW COMMUNICATION BETWEEN THE NODE (10) AND A WIRELESS NODE (10) OF THE NEIGHBOURING NETWORK.
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).
