Existing research on data collection using wireless mobile vehicle network emphasizes the reliable delivery of ***,other performance requirements such as life cycle of nodes,stability and security are not set as primary design *** makes data collection ability of vehicular nodes in real application environment *** considering the features of nodes in wireless IoV,such as large scales of deployment,volatility and low time delay,an efficient data collection algorithm is proposed for mobile vehicle network *** adaptive sensing model is designed to establish vehicular data collection *** protocol adopts group management in model *** vehicular sensing node in group can adjust network sensing chain according to sensing distance threshold with surrounding *** will dynamically choose a combination of network sensing chains on basis of remaining energy and location characteristics of surrounding *** addition,secure data collection between sensing nodes is undertaken as *** simulation and experiments show that the vehicular node can realize secure and real-time data ***,the proposed algorithm is superior in vehicular network life cycle,power consumption and reliability of data collection by comparing to other algorithms.

关键词： wireless vehicle network datacollection protocol network sensing chain self'-adaptive sensing sensing distance threshold.
