Looking for Omnet++ expert

Requesting two complete scenarios that can be run within OMNeT++, COA-A and COA-B (course of action). Project will contain the appropriate .ned files, code, and other dependencies necessary to successfully run both scenarios and capture end-to-end transmission times. Each COA will contain a last-hop WSN node that will transmit a signal, a gateway that will converge the ZigBee and 4G-LTE protocols; and three 4G-LTE hosts: the eNodeB, the S-GW, and the P-GW. I'm very flexible with the composition of the WSN node and all 4G-LTE hosts. However, the internal protocol stacks must be accurate. The only difference between each COA will be the composition of the gateway and the internal protocol stacks of the WSN node.
