Title Large-scale sensor networks Design and implementation of efficient transport mechanism
Abstract
With the post-PC era into the widespread use of laptop computers, cell phones, PDA, GPS receivers and other intelligent electronic products, miniaturization and modernization of embedded systems everywhere. Wireless sensor network is one of countries in the field of information to explore the hot, ZigBee technology as a two-way short-range communications technology, with its low complexity, the advantages of low power, low cost, ad hoc networks, etc., are widely used in many practical applications.
Based on the CC2530 ZigBee protocol stack and the design of wireless sensor network nodes, the paper will first introduce the features of ZigBee technology, network topology, protocol analysis. By integrating the zigbee technology is applicable to the characteristics of the data acquisition system, based on the theory zigbee technology to collect data on the statement of principle of data acquisition systems, and then discusses the design method based on hardware and network design cc2530 chip data acquisition node coordinator the establishment of software design approach network, node joins and leaves the network. Introduction ZigBee protocol stack, drawn coordinator, routing node and sensor node software flow chart form a mesh structure of the sensor network. Finally, build a network with serial testing tools to detect, process and sensor network nodes to establish the main subject test network node data transfer.
