Omnet+ specialist needed to build Zigbee topologies

I am looking for a specialist who can help me rebuild 3 simple ZigBee topologies using OMNeT++ (Maybe MiXim framework, too) ASAP. I am not a pro at this, so maybe I will need your guidance.

The goal is to have 3 separate folders for each ZigBee topology - star, tree and mesh. So I could manually do a reasearch on each one of them.

The network must work in EU 2.4 GHz frequency band. Info about topologies (added visuals in attachments):
- Star topology must have 1 network coordinator, 2 routers and at least 5 end nodes.
- Tree topology must have 1 coordinator, 4 routers and 5 end nodes.

- Mesh topology must have 1 coordinator, 5 routers and 1 end nodes.
Every connection between the nodes must be WIRELESS.



The aim for this work is to compare each topology through investigation of:
- throughput,
- end-to-end delay,
- packet loss rate,
- traffic sent and traffic received depending on the topology,
- energy consumption in each topology for transmit and receive mode.
