A novel communication protocol for wireless short command

There is an increasing demand for low-cost large-scale wireless protocol for control system. Currently adapted wireless protocols aim at high data rate applications and hence do not provide the most cost-effective solution. Hence we see that there is room to explore and optimize for an efficient protocol for consumer wireless automation control. In our protocol, we target at low-cost, robust, high efficiency and high security. The developed protocol has been embedded into low-cost micro-controllers and is ready to be applied to applications such as light switches, air-conditioners, curtains, audio and video systems, microwave ovens, washing machines as well as security systems. A wireless control system was implemented and an experiment was set up to test the performance. More than two hundred devices were tested. Analysis showed that, in most scenarios, a typical transmission delay of 80 ms per command was experienced. The protocol was found to be robust, simple-structured and yet efficient. It should be noted that the cost for the embedded solution is about USD2.00. The protocol is designed for interoperability and the completed protocol is ready to be plotted onto most consumer products.
