一种异构WSN复合型栅栏覆盖方法研究

Heterogeneous WSN with Compounded Barrier Coverage Method

WSN栅栏主要应用于各个领域的入侵检测,然而传统的栅栏覆盖方法未充分考虑天气对栅栏功能的影响.针对该问题提出一种异构WSN复合型栅栏覆盖方法(A Heterogeneous WSN with Compounded Barrier Coverage Method,HCBC),该方法能够满足晴雨天不同天气状况下的入侵监测要求.通过在监测区域内部署两类传感器节点,首先利用普通传感器节点构建晴天适用的栅栏,然后派遣增强节点根据普通栅栏的框架完成雨天栅栏的构建,使得构建的栅栏具有较好的鲁棒性,且保证在两种栅栏的构建过程中能耗优先.仿真实验结果表明该方法构建的复合型栅栏能够在晴天和雨天场景中有效发挥入侵监测功能且平均覆盖率比传统方法提高了55.35%.

WSN barrier are mainly used for intrusion detection in various fields,however,it has not fully considered the factor of weather.To solve this problem,a heterogeneous WSN with compounded barrier coverage method for this task is proposed,which can meet the intrusion detection demand under different weather conditions.In the proposed method,two sensor nodes are deployed within the detection area.First,barrier for sunny days would be constructed by ordinary sensor nodes.Then,based on the framework of ordinary barrier,enhanced nodes are dispatched to construct barrier for rainy days.Therefore,the barrier has better robustness as well as energy priority in the process of construction of these two barriers.The experimental results show the introduced method is effective for intrusion detection in sunny or rainy days and its average coverage rate has increased by 5.35%than traditional methods.
