ZigBee is a low-rate control network communication protocols which designed for the wireless sensor networks with low power consumption, low cost, low complexity, safety and reliability characteristics, and thus have a broad market prospect. ZigBee PHY layer and MAC layer protocol used IEEE802.15.4. This paper analyses the function of MAC layer in IEEE 802.15.4, introduces the process of design and...
The experiment in computer composition and maintenance course is great loss of equipment and it would be more loss for new equipment, in addition the funds is an acute lack in a university and college in China. there are lot of out-of-date equipment which are weeded out with years, but these equipment cannot be used directly to this experiment. this paper offered a proper methods by the analysis of...
This paper first introduces negative selection algorithm of artificial immune system and non-dimension-parameter, and then designs the unit fault diagnosis system software based on artificial immune system by combining negative selection algorithm and non-dimension-parameter. The advanced nature, practicability, validity and correctness of the idea on software design are proofed by the experiment...
