Network topologies

The choice of the network topology can decisively influence the performance and system stability of your network. Sleeping nodes or an non-static environment can compromise function depending on the network structure.  

Routing in networks ensures that data arrives at its destination using the optimum path.  If there are alternative paths to the individual nodes, the function of the network remains even if individual nodes malfunction.  


Point-to-point

  • most simple topology used as wire substitute
  • all nodes are connected to each other directly, coordinator is not needed
  • low failure safety



Star

  • all nodes communicate via PAN coordinator
  • low failure safety
  • e.g. for short range applications

Peer-to-peer

  • every nodes has to be within the RF range of the PAN coordinator
  • good failure safety
  • e.g. for short range applications

Cluster tree

  • parent-child-connection, derivate of the star topology with additional hops
  • good failure safety because of self-healing network
  • suitable for long range applications

    Mesh

    • combination from peer-to-peer and cluster tree structure
    • all nodes have equal rights among each other
    • good failure safety because of self-healing network
