Creating a reliable network topology is a very important aspect in building your WSN SYSTEM. You should carefully consider network topologies and data COMMUNICATION paths when setting up a WSN system. 

To ensure maximum network reliability, National Instruments suggest that you adhere to the following criteria:

• Without the use of router nodes, no more than 8 end nodes can connect directly to a single gateway
• Using router nodes, each gateway can connect to a maximum of 36 total nodes (routers + end nodes combined)
• No more than 8 end nodes can connect to a single router node
• Each end node should be no more than 3 hops away from the gateway
• To achieve the greatest amount of end nodes, NI suggests a topology CONSISTING of one gateway, four router nodes, and 32 end nodes (eight end nodes for each router). To achieve the greatest coverage distance, NI suggests a topology consisting of one gateway, eight router nodes, and 28 end nodes (SEVEN end nodes for each second-tier router). 
• The NI WSN protocol is built on a self-healing network, meaning that the network will automatically re-configure if necessary. Because of this, it is important to analyze all network POSSIBILITIES and maintain the 8:1 child-to-parent ratio for all network possibilities when designing your WSN topology.
