Abstract


With the improvement of living standards , the requirements of wireless technology is getting higher and higher , and the emergence of ZigBee wireless technology to some extent to meet people 's special occasions ; it has a low cost , low power consumption , high security , stability strong , free bands and so on , with a wide range of application areas ; here we are with the ZigBee technology and radio frequency chip CC2430 development of wireless conference voting system . Protocol stack and the network structure of ZigBee technology with the NS-2 to expand ZigBee network performance simulation analysis , we were three different structures of ZigBee network simulation . 1 star network , we start from the time the formation of the network analysis , prioritization mechanism to shorten the time of network formation , and propose a prioritization method , then the method of repeated simulation experiments , experiments data to validate its usefulness ; then on the the star network data packet delivery ratio and packet transmission delay analysis . Tree-structured network , in tree contains RN and RN- device network simulation , and then only RN - containing equipment tree network simulation analysis to analyze the performance parameters the ZBR and the AODV routing algorithm network performance. The 3.MESH in the structure of the network , we have more nodes and larger regional network simulation and simulation analysis and the MESH unique network repair function . The final paper uses a combination of zoning and time slot polling mechanism to solve the conflict of the network data . ZigBee network simulation analysis , we begin to wireless conference voting system detailed design . First, the introduction of the overall design of the framework and technical architecture ; then designed manually initiate network , and modify the protocol stack, network layer and application layer configuration , three different network structure switching selection and application tasks add ; Next, we design serial control procedures to achieve single- cast and multi- cast mode switch ; Finally, the specific functions of the nodes in the network design and implementation , and then conduct the test .
