We analyzed the channel utilization of Common Control Channel (CCC)-based wireless protocol
. An efficient estimation algorithm for the number of devices on a wireless channel is designed to optimize the utilization based on our analysis. Our proposed protocol outperforms other protocols significantly, especially when the number of devices is large and in a state of dramatic fluctuation. Our work was accepted and presented in IWCMC 2013
, and was selected for publication in the WCMC journal
. Further improvement of the protocol is achieved by adopting the asynchronous resource reservation concept.
The figure above shows an example of the channel reservation result by our extended protocol. 20 machines, labeled from 0 to 19, are communicating on 1 CCC and 4 data channels. The length and arrival time of each packets are randomized to simulate real-world scenarios. The result shows that the data channels have been fully utilized and thus optimized the utilization.
