Network design for short command

Abstract

The growth of wireless short command network is expected to accelerate in the near future and there is an increasing demand for low-cost and secure wireless system for control applications. Currently adopted wireless protocols such as WLAN and Bluetooth technology aim at medium to high data rate applications and hence do not provide the most cost-effective solution. Hence there is room to explore and optimize an efficient protocol for wireless Short Command Control (SCC). In this research, the design of a low-cost, robust, high efficiency and high security protocol is targeted. A wireless control system was implemented and an experiment was set up to test the performance. Testing showed that when devices are located within the residential area, normally referring to a distance of 10 meter, a typical transmission delay of 0.13 second per command was experienced. The system was found to be robust, simple-structured and yet efficient for most of SCC applications.
