Issue in communication

[Rabia Ahmed]

Hello,

Can anyone help me, why few nodes not receive data/message as it show Rx None? What are the possible reasons? I am using 1000 by 1000 area.
Is this issue arise due to large are, duration or anything else?
Thank you.

Could you tell us more about this simulation? It seems wireless comm but is it wifi? lte? 5G?
I suppose it's a failure of MAC scheduling or simply a lack of received power.

If it's 5G (& especially in dense scenario), the priority queue may be reset before all users received their packets.

So some users' throughputs will be eternally 0.

Thanks

Yes it is wifi. As you said it may be failure of MAC or received power, so how can I fix it? I will try both.

With WiFi and such a large area you need a multi hop routing algorithm (like AODV). Check examples/routing/manet-routing-compare.cc for ideas.

Mind that, even with a proper routing algorithm, you still need some conditions (e.g., a connected topology), and collisions & local congestions might still hinder packet reception.

Thank you.

>> failure of MAC or received power, so how can I fix it?

What I said about MAC & priority queue are 5G's matter, so now you can forget them.

If it's due to receiving power, simply you have to set more Tx power or shorten the Tx-Rx distance. Check your setting.

Thank you.
