Wireless Mobile Sensor Network Time Synchronization Technology

Wireless sensor networks (WSN) system is very much at home and abroad now of hot point research realm.. Because it synthesizes wireless correspondence and moves correspondence, calculator technique and wireless to spread feeling machine etc. to involve various technique realm, its emergence brings people numerous conveniences, for realization automation, no man turn to provide technique support. It is knowledge height integration, and is a technique content height cross of academics.For wireless mobile sensor network time synchronization, time synchronization techniques described the classification and research status at home and abroad, and pointed out that the technology trends.Details wireless mobile sensor network technologies and discuss the architecture of wireless sensor, wireless mobile sensor network composition and characteristics and applications. The composition from the sensor nodes to the sensor network protocol framework, topology; wireless mobile sensor network characteristics and performance; related to the relevant standards, wireless mobile sensor network in the application of the relevant areas.The introduction spreads a feeling machine network time synchronous request, then mainly introduce a few kinds the synchronous mechanism that use already now is at home and abroad, for example:RBS, DMTS. carry on their merit and shortcoming a comparison, mainly is the aspect of structure, synchronous keys, such as way and error margin...etc. that constitutes in the loss, network of energy.Only understand they use of environment, carry on the analysis to all circumstances, just can synchronously and up attain to time more excellent.In explaining several wireless sensor network time synchronization mechanism, based on the proposed hierarchy based on wireless mobile sensor network time synchronization methods, and detailed analysis of the networking process. Analyzed the characteristics of the sensor network time synchronization, topology, and synchronization process to establish, on synchronized on the period of the study.Finally, intelligent logistics network is proposed based on a hierarchy of time synchronization hardware and software platform to build programs and programming design methods, implementation process, and finally through the actual testing, validation, hierarchical structure based on the superiority of the time synchronization mechanism.
