+##### Scenario
+# The simulated scenario comprises 1 that wakes up randomly
+# for a duration called "uptime" every hour. The sender try to transmit
+# his data during that uptime. Other nodes are receivers that have similar
+# random wake up parterns and strive to receive data from the sender.
+
+##### Bandwidth matrix
+# Bandwidth value can be 0 for unreachable nodes
+# Diagonal entries impact the transmission duration for wireless transmissions (wlan0)
+n=2 # Number of nodes including the sender
+B=np.full((n,n),5) # 5Mbps
+
+##### Latency matrix
+# If the latency entries match one with a bandwidth of 0
+# then it will be ignore since node is unreachable.
+L=np.full((n,n),0) # 0s
+
+##### Create the simulator
+s=esds.Simulator(B,L)
+
+##### Instantiate nodes
+uptime=180 # 180s uptime
+s.create_node("sender",args=uptime) # Load sender.py for the first node with 5 as argument (first row in B and L)
+
+# Aguments can be passed to nodes via: s.create_node("sender",args="my argument")
+for n in range(0,n-1): # Load receiver.py for the remaining nodes
+    s.create_node("receiver",args=uptime)
+
+##### Run the simulation
+#s.run(debug=True) # Generate a "esds.debug" file
+s.run()
