Leach algorithm Question

[kousheshy]

Hi Everyone.

I have problem with part of LEACH algorithm, this is what wrote in clustering part of LEACH algorithm:

Each node that has elected itself a cluster-head for the current round broadcasts an advertisement message to the rest of the nodes. For this “cluster-head-advertisement” phase, and all cluster-heads transmit their advertisement using the same transmit energy. The non-cluster-head nodes must keep their receivers on during this phase of set-up to hear the ad- vertisements of all the cluster-head nodes.

I just have a question about "Cluster-Head advertisement message to the rest of the nodes".

Is this message sent to all the nodes in the network? for example all 150 nodes in 200 x 200 region?? or just nodes in Cluster head range? i think it's not efficient, i try to do same on my thesis but i think it's not logical !! can someone explain this to me? if it just broadcast to nodes within it's range what is best range for Node?

thanks.

Hi Kousheshy,

This article is on NI WSN topology setup. I don't think it is exactly what you are looking for, but I think it will help.

Also, this forum is primarily used for discussing NI products. You are welcome to ask more general questions here, but in this case, you might get a better answer if you ask your professor or your classmates.

Thanks RenKylo2.

Yes it seems i must ask my professor..

no, the message will be only sent to the nodes that are in the cluster head range

yes. thanks!
