摘要:

移动群智感知(MCS,mobile crowd sensing)是一种有效利用智能移动终端协同采集环境数据的技术,集成多种传感器的移动载体(如车辆)越来越多地被当作参与者来承担各种感知任务。在智慧矿山物联网(IoT,Internet of things)中,为了更好地感知人—机—环的实时信息,支撑安全生产顺利进行,基于MCS思想对矿山环境下移动感知节点的覆盖质量和能耗优化进行研究,提出了一种综合考虑覆盖率(CP,coverage percentage)和覆盖密度(CD,coverage density)的效用函数F(?)来衡量MCS的覆盖质量。为了获得最优的覆盖质量,针对参与感知的车辆选择问题提出了一种改进的贪婪算法——覆盖质量优化(CQO,coverage quality optimization)算法来优化覆盖质量,并使用真实的车辆轨迹数据集对所提出的算法进行评估,研究了影响覆盖质量的几个因素。实验结果表明,该算法具有较好的覆盖质量。

Abstract:

Mobile crowd sensing (MCS) is a promising diagram for the environmental information collection based on the smart mobile terminal.Nowadays,vehicles with multiple embedded sensors are increasingly being considered as participants to complete various sensing tasks.In order to better perceive the data in the coalmine environment,the coverage quality and energy consumption of the perception data of sensing terminals were studied based on MCS.A new sensing coverage quality indicator called utility function F(?) jointly considering the coverage percentage and coverage density was defined.The selection of vehicles as an optimization problem to improve the coverage quality was formulated,then an improved greedy algorithm-coverage quality optimization (CQO) algorithm was proposed.The proposed algorithm with the real vehicle trajectory dataset was formulated and several factors influencing the coverage quality were studied.The experiment results show that the proposed algorithm achieves a better coverage quality.

Key words: smart coalmine, mobile crowd sensing, coverage percentage, coverage density
