Abstract. 
As many research papers show, one of the problems of a LoRa network is its limit regarding 
the scalability. However, these papers also indicate that it is possible to achieve 
the scalability for them by dynamically selecting transmission parameters and/or by employing 
multiple gateways. In this paper, we build upon the latter solution and show that although 
data extraction rate in such networks is quite good, it suffers hugely from data duplication 
on the communication path between the gateways and network server. In remote areas, 
the gateways are usually connected to a network server by cellular networks, which yields
additional transmission costs. In LoRaWAN network topology, the gateways are not  connected 
to each other and therefore cannot actively filter the traffic prior to sending it 
further downstream. Thus, we propose a randomized algorithm allowing to reduce duplication 
of the packets sent to the network server without communicating with other gateways.
