Wireless Sensor Simulation || Matlab

I need simulation of wireless sensor network in matlab with following details.

Network Generation (specifics are provided but it should be flexible and with user input.):
* The network should have multiple nodes in an specific area (e.g. 100m x 100m)
* All nodes should have same wireless range (e.g. 50m) and it should be visible e.g. blue circle around each node.

Simulation (Neighbor Detection and Communication Establish):

* This process would start from center node which we can set explicitly from code. It will first detect all its neighbors within range and they would establish bidirectional communication.
* Then same process would be done by its neighbors one by one. Similarly all nodes would detect and establish communication level wise.
* Topology should follow tree approach, so if there are any redundant links between branches, they should be discarded.
* At the end we should be able to have communication between all nodes. For confirmation, all nodes should be able to send current time with their node label.

Result:
* For result we should get a separate window showing nodes in tree topology.
* We should also get array for each node, containing name of all its neighbor nodes.

I have multiple tasks linked to the project. If you can deliver the project timely and correctly we can work on more projects as well.
Setting up and training to use matlab for this project would also be part of this project.
