I need all sensor nodes to send the same signal to one node with ID=1. How can we determine which node is of ID=1.Thanks
You can assign ID as network address or you maintain this in application layer.
In case of Application layer, create your own application layer packet format and add a field with ID as destination. While sending packet from application layer you could add 1 as destination number in this field ...
Thank u Khandakar, but how can I assign the ID as network address, since I need to implement a hardware.
You can assign in application layer. Could you please tell me the hardware platform that you choose to implement
Hi, If you are programming the nodes using TinyOS, you can inf act assign node IDs to every sensor node. Now if the received packet is intended for a specific node D, only that node will receive it, the others will simply ignore the packet!
I have used TI CC2531 with zstack. However, I am 100% sure, you could be easily able to add ID at least from application layer.
Thanks Khandakar n Farooq.I think i should applu both ur answers. That to assign an id for each node. Then I write in my programming code that all nodes should send to node 1,
In WSN there is per-define macros are there which give you the id of the particular node so that you can get the identity of the node.
MACROS: self, SELF_NETWORK_ADDRESS,,BROADCAST_NETWORK_ADDRESS
Dear Researchers, Can you please guide me if there is implementation of GIS in WSN??? If yes then how?
Hi,
In order to be complitely network independant : ipv4 ipv6, I prefer to use the MAC address. And as a good thing the MAC address is part of the ipv6 address.
sincerely.
