These are instantaneous delays for different size networks. All 16 ZigBee channels are
assumed to be available. Simulation procedure is the following: we allow the algorithms to reach
a certain point. At that point, a packet is generated in the network. The instantaneous delay is then
the delay of this packet. In these figures, the delays are averaged over 400 packets per run and 100
runs are executed
5.7 Simulation Results
In this section, we present some simulation results. In Fig.
5.5
the instantaneous
delay for different situations is shown. Here, all 16 channels are assumed to be
free of IEEE 802.11 interference. It can be clearly seen that the ASA algorithm
outperforms the RB algorithm. Not only does it reach an optimal steady state (no
exploration and all nodes on the same channel), it also converges significantly faster.
